Adaptive multishot canceler for wideband CDMA systems

Adaptive multishot canceler for wideband CDMA systems

IEEE VTS 50th Vehicular Technology Conference, VTC 1999-Fall

With the demand for high capacity (multimedia) services, wideband CDMA (WCDMA) has become an attractive multiple access scheme for 3rd generation wireless systems. Coming with higher data rate, the application of WCDMA brings with it new challenges in terms of multiple access interference (MAI) and inter-symbol interference (ISI) suppression due to the fact that compared to the 'regular' CDMA, the delay spread is no longer only a few chips. Most of the literature on multiuser detection so far focused on algorithms which, due to high computational/hardware complexity, are unsuitable for large delay spread channels. In this paper, we present an adaptive symbol-based signal separator based on multishot matched filtering which is suitable for the asynchronous large delay spread fading channels characteristics. © 1999 IEEE.

The "Bootstrap" algorithm provides an efficient adaptive multi-user detection approach to solve the near-far problem in CDMA communication systems. The weight vectors are controlled by a simple decorrelation scheme which minimizes the correlation between their outputs and the hard limited version of the other outputs, respectively. It has been shown that the "Bootstrap" algorithm provides performance similar to that of MMSE with low complexity. In this work, the convergence and stability of the "Bootstrap" algorithm is considered. Sufficient conditions for the code cross-correlation and the step size are provided.

ISBN: (纸本)0780356683

This paper investigates the performance of a new adaptive call admission policy based on a window-measurement estimation of the status of the buffer at the base station where two classes of customers (voice and data) are multiplexed into L servers. In this work, we interrelate physical limitations of the base stations (i.e., the number of transmission and reception modems), call and burst level traffic, instantaneous ATM buffer conditions, and end-to end bit error performance. Considering these parameters, we combine them all in one queueing problem and devise a new hybrid congestion based call admission policy. This policy is investigated in conjunction with CDMA integrated networks utilizing the IS-95 transmission/reception platforms. The results show that the proposed policy does maintain the QoS required for the networks under expected traffic load. © 1999 IEEE.

We present a novel method for designing polynomial FIR predictors for fixed-point environments. Our method yields filters that perform exact prediction of polynomial signals even with short coefficient word lengths. Under ordinary coefficient truncation or rounding, the prediction capability degrades, or may be totally lost. With the proposed method, the filters are designed so that the predictive properties are exactly preserved in fixed-point implementations. The proposed filter design method is based on integer programming (IP) and can be directly applied to any fixed-point FIR design specifications which can be formulated in a form of linear constraints on the filter coefficients. © 1999 IEEE.

With the increasing demands of power efficiency and linearity on power amplifiers (PAs), there are more and more demands for some new and easy modeling methods of PA nonlinearities. One direction of these trends is to get better polynomial models which are extensively used in the design of analog predistorters(PDs) to combat nonlinearity and in the estimation of the intermod-ulation products for PAs. Because of the difficulty in modeling a PA and for ease of comparison, most of the polynomial models reported in the literature are based on a simple TWTA model(Saleh's model) instead on actual PA devices. In this paper, we propose a method for obtaining a general order polynomial model from an existing model such as Saleh's model, or from the input-output statistical characteristics of a PA device. We also obtain the analytical representation of its coefficients. The method is based on minimizing the power of the distortion between the output of a PA and the output of the model based on it. Thus the model is named as minimum distortion power polynomial model(MDP-PM). We have obtained the coefficients of the proposed MDP-PMs up to order 7 based on Saleh's model to illustrate our results. Then we show the application of this model in analog PD designs, whereas the resulted PD devices outperform those given in the literature by 0.8db for order 3 and by 0.2db for order 5. © 1999 IEEE.

Multi-code CDMA (MC-CDMA) is proposed as an alternative multiple access scheme which provides the flexibility, high data rates, and bandwidth-on-demand features necessary in next-generation wireless integrated services networks. In a conventional MC-CDMA configuration (e.g., in IS-95B) a user can transmit information in multiples (M times) of a basic data rate by using M orthogonal supplemental DS-CDMA channels. In this paper, motivated by the remarkable performance of turbo codes with large interleaving lengths in AWGN channels, we investigate the performance of a MC-CDMA system employing different concatenated encoding schemes combined with iterative decoding. Furthermore, we examine the frame error rate performance of the various schemes by considering CRC codewords in each of the M frames corresponding to each data block. We show that coding and interleaving at the block level improves the block error rate (BlER) performance, especially when turbo schemes are used, while the extra CRC overhead is beneficial mainly when convolutional codes are used.

We consider wireless communication systems that employ multiple transmitting and receiving antennas to achieve spatial diversity and to increase the data rate through fading channels. In particular, we focus on a system with N transmitting antennas and M receiving antennas. We consider the design and performance evaluation of several detection algorithms for recovering the original data from the received signals on the M antennas. These algorithms include the optimum maximum likelihood detector and suboptimal reduced-complexity detectors such as the MMSE detector and a detector based on maximal ratio combining. We also consider coded systems.

The remarkable performance of turbo codes for low SNRs in AWGN channels has encouraged the application of turbo codes to systems operating in different kind of channels. In this paper we consider an IS-95-based CDMA system operating in a multipath Rayleigh fading channel. We replace the convolutional encoder by a parallel and a serial turbo encoding scheme, and by a serial concatenation of an outer convolutional and an inner parallel turbo code, and instead of the Viterbi decoder we use iterative decoding based on the MAP algorithm. We perform BER and FER comparisons by varying system parameters such as the constraint length of the component convolutional codes, the interleaver lengths, and the wireless channel fading rate. The results obtained show that the concatenated schemes outperform the more complex convolutional scheme even for relatively short interleaving lengths, especially when FER is the desired figure of merit.
