3rd international symposium on Wireless Communication Systems (ISWCS 2006)

After 3G mobile and wireless systems take-up, the research community is now directing its interest towards unified ways of looking at system design, optimization, and Quality of Service (QoS) issues to satisfy the requirements of next generation multi-service mobile and wireless IP-based networks. Their implementation requires the development of IP QoS arquitecture and mechanisms encompassing the various layer of the OSI Model to cope with the new requirements. This work identifies the requirements on latency (link radio), latency (end-to-end), bit error rate, data rates, and traffic characterisation for mobile multimedia network beyond 3G. Characterisation parameters were identified and values were suggested for their range of variation, in the context of cross-layer design.

3rd IEEE international Workshop on Electronic Design, Test and Applications

ISBN: (纸本)0769525008

The co-design of hardware and software systems with object oriented design languages like SystemC has become very popular. Static analysis of those descriptions allows to conduct the design process with metrics regarding quality of the code as well as with estimations of the properties of the final design. This paper shows the utilization of software metrics and the computation of high level metrics for SystemC, whose generation is embedded into a complete design methodology. The performance of this analysis process is demonstrated on a UMTS cell searching unit.

For the WCDMA/HSUPA concept, a key to ensuring high spectral efficiency is to correctly adjust the transmission power ratios among the data and control channels. This paper provides optimal values for the power ratio between the Enhanced-Dedicated Physical Data Channel (E-DPDCH) and the Dedicated Physical Control Channel (DPCCH) from a Link Efficiency (LE) point of view. LE has been defined as the ratio between the average number of correctly received bits per second and the average total transmitted power. The optimization was carried out by testing different E-DPDCH to DPCCH power ratios in an HSUPA link level simulator for different bit rates. This simulator includes Hybrid ARQ (HARQ) and optimal power ratios are extracted for different Retransmission Sequence Number (RSN) targets. For Vehicular-A 30 km/h conditions, the optimal power ratios per code show only minor dependency on the bit rate (typical values ranging from 8.1 to 9.9 dB) and the RSN target (maintaining or decreasing their value as the target increases). These results show that it is more link efficient to increase the DPCCH transmission power with the bit rate (and the E-DPDCH's by applying the power ratio) than to maintain a constant DPCCH transmission power and just increase the EDPDCH to DPCCH power ratio.

The productivity of machine tools is significantly improved by using microcomputer based CAD/CAM systems for NC program generation. Currently, many commercial CAD/CAM packages that provide automatic NC programming have been developed and applied to various cutting processes. One of the cutting processes machined by CNC machine tools is hole-cutting operations (HCO). In this paper, we attempt to find an efficient solution approach to determine the best sequence of operations for a set of holes that located in asymmetrical locations and different levels. In order to find the HCO that achieves the shortest cutting tool travel path (CTTP), Genetic algorithm is introduced. After the CTTP is optimized, the G-codes that use to code the part of program for this process is created. CTTP can be formulated as a special case of the traveling salesman problem (TSP). The incorporation of genetic algorithm and TSP can be included in the commercial CAD/CAM packages to optimize the CTTP during automatic generation of NC programs.

3rd international symposium on Precision Mechanical Measurements

The Evolutionary Algorithm (EA)-Genetic Algorithm (GA) was improved to evaluate the form and position errors that were summarized as nonlinear optimization problems. The key techniques in the implementation of the GA have been studied in detail. The emphasis was on the fitness functions of the GA concerned with the concrete problem so that they were proposed first. Second the expression of the desired solutions was discussed in the continual space optimization problem. Because different expression was suitable for different problem, here the real numbers were used to express the solutions to find which were called as chromosomes in the GA. Third the improved evolutionary strategies of GA were described respectively on emphasis. They were the selection operation of Odd Number Selection plus Roulette Wheel Selection, the crossover operation of Arithmetic Crossover Between Near Relatives and Far Relatives, and the mutation operation of Adaptive Gaussian mutation. The evolutionary strategies determined the update of the whole population and the terminal solution. After operations from generation to generation, the initial stochastic population on the basis of the least squared solutions would be improved until the best chromosome/individual appeared. Finally some examples were computed to verify the devised method. The experimental results show that the GA-based method can find the desired solutions that are superior to the least squared solutions and almost equal to those given by other optimization techniques except a few examples give a similar result.

It is wildly recognized that whether the selected kernel matches the data controls the performance of kernel-based methods, Ideally it is expected that the data is linearly separable in the kernel induced feature space, therefore, Fisher linear discriminant criterion can be used as a kernel optimization rule. However, the data may not be linearly separable even after kernel transformation in many applications, a nonlinear classifier is preferred in this case, and obviously the Fisher criterion is not the best choice as a kernel optimization rule, Motivated by this issue, in this paper we present a novel kernel optimization method by maximizing the local class linear separability in kernel space to increase the local margins between embedded classes via localized kernel Fisher criterion, by which the classification performance of nonlinear classifier in the kernel induced feature space can be improved. Extensive experiments are carried out to evaluate the efficiency of the proposed method. © Springer-Verlag Berlin Heidelberg 2006.

A new linear block code construction technique is proposed [1]. It generates all the even codes of length greater than 8 with full information rate for Hamming distance-4. The codes generated by the proposed method include the extended Hamming codes and the Reed Muller codes of distance-4. The generator matrix has useful properties such as lowest density, quasi-cyclic and regular.

Multi-carrier code division multiple access (MC-CDMA) is a modulation scheme that combines the advantages of OFDM and CDMA to provide robustness against frequency selectivity in wireless channels. Arrayed MC-CDMA systems combine MC-CDMA and antenna array technology to harness the spatial and temporal 'signatures' of received signals, thus making it possible to realize high transmission rates envisioned for next generation wireless communications. Localized scattering, which occurs for each multipath, motivates the frequency selective wireless channel to be modelled as a diffused vector channel. In this paper, space-time diffused vector channels for arrayed MC-CDMA systems are modelled and analyzed. Simulation studies show that the use of this diffused channel modelling in arrayed MC-CDMA receivers yields better bit error rate (BER) performance than receivers that ignore the presence of spatial and/or temporal diffusion.

In this paper, we conduct performance comparison of rate compatible parallel concatenated convolutional code (PCCC) and serially concatenated convolutional code (SCCC) in additive white Gaussian noise (AWGN) and frequency selective fading channels. Series of computer simulation results show that the packet error rate (PER) performance of memory 2 SCCC is worse than that of memory 3 PCCC by 0.4-0.8 dB at 10 -2 PER after the sufficient number of decoding iterations, whereas the complexity of SCCC is lower than that of PCCC by about 39%. Increasing the memory length in SCCC does not lead to performance gain. On the other hand, reducing memory length in PCCC leads to significant performance degradation. However, reducing the number of iterations to half in PCCC leads to lower complexity than SCCC and still offers better PER performance than SCCC in terms of the required E b /N 0 for 10 -2 PER. Therefore, PCCC can achieve better trade-off between complexity and performance than SCCC.
