In this paper, the effect of WWW traffic on the functionality of a resource metric estimator applicable to a TDD-CDMA system incorporating a multirate transmission scheme (multicode and multislot) with simple call admission control algorithm is investigated. A solution for efficient inter-working between the physical layer and the higher layers, a resource metric mapping function (RMMF) that can deliver information about the state of the current channel load condition by monitoring the mean of SIR bursts and also the availability of a code pool by estimating the standard deviation of SIR bursts is proposed. This function is defined and demonstrated by means of an average raw BER mapping diagram as a function of the mean and the standard deviation of SIR bursts according to the multirate transmission method. By using this kind of mapping function combined with throughput estimation, radio resource allocation algorithm can successfully reflect the current interference and mobile radio channel characteristics.

For fault diagnosis, signal singularity and irregularity discontinuity fraction are very significant characteristics of signal. The discontinuity of output signal represents a system fault . In an angular measuring system, function transformer uses two D/A convertors, output circuit fault of a D/A convertor brings about discontinuity of one phase input voltage amplitude of inductosyn, results in a system error exceeding the allowable error and reduces the system accuracy. This is the reason why discontinuity is detected. Fourier transform has no resolution ability in angular domain, but wavelet can analyse signal in angular and frequency domains. So we decompose the error signal of angular measuring system by wavelet, detect the signal singularity at high frequency layer and find out the accurate position of it.

In this paper we consider the robust performance properties of some integrated flight and propulsion controllers for a large transport aircraft, designed using three different H/sub /spl infin// methods. The controller design methods compared are H/sub /spl infin// loop shaping, two-block mixed-sensitivity and four-block mixed-sensitivity. The study provides an interesting practical illustration of the consequences of pole-zero cancellations in certain H/sub /spl infin// control designs.
