The study on GSC(M, L) receiver is also important from a theoretical standpoint because this model encapsulates both the classical selection diversity and maximal-ratio combining (coherent detection) or post-detection equal-gain combining (noncoherent detection) receiver structures as limiting cases. We first derive a concise analytical expression for the moment generating function (MGF) of the GSC(M, L) output signal-to-noise ratio with independent and identically distributed diversity paths over Rician fading channels (in terms of only a single finite range integral whose integrand is composed of tabulated functions). Previous studies have only treated either Rayleigh or Nakagami-m (1960) channel models using numerous ad-hoc approaches to simplify an M-dimensional nested integral that arise in the computation of the MGF. The novelty of our mathematical framework for computing the MGF relies on the fact that it allows us to treat all common multipath fading channel models (Rayleigh, Rician, Nakagami-m and Nakagami-q) in a unified sense, it leads to a much More elegant and computationally efficient expression than those available in the literature, and it holds for any combinations of M and L values. Using this newly derived MGFs, we provide a unified error probability analysis for many coherent and noncoherent digital modulation/detection schemes in a myriad of fading environments.","PeriodicalId":159750,"journal":{"name":"Vehicular Technology Conference.

In the proposed MMSE combining scheme, the combining weight of each sub-carrier component is accurately estimated from the channel gain, noise power, and transmission power ratio of all the code-multiplexed channels to the desired one, by exploiting the time-multiplexed common pilot channel in addition. to the coded data channel. Simulation results elucidate that the required average received signal energy per bit-to-noise spectrum density ratio (E/sub b//N/sub 0/) for the average packet error rate (PER)=10/sup -2/ is improved by 0.6 and 1.2 dB by using the proposed MMSE combining Instead-of the conventional equal gain combining (EGC) in a 24-path Rayleigh fading channel (exponential decay path model, maximum delay time is approximately 1 /spl mu/sec) in an isolated cell environment, when the number of multiplexed codes = 8 and 32, respectively, with the spreading factor of 32. Furthermore, when the average received E/sub b//N/sub 0/=10 dB, the achievable throughput, i.e., the number of simultaneously multiplexed codes for the average PER=10/sup -2/ in the proposed MMSE combining, is increased by approximately 1.3 fold that of the conventional EGC.","PeriodicalId":159750,"journal":{"name":"Vehicular Technology Conference.
