—In this paper, we develop an analytical framework to quantify the effects of the spreading bandwidth (BW) on spread spectrum systems operating in dense multipath environments in terms of the receiver performance, the receiver complexity, and the multipath channel parameters. The focus of the paper is to characterize the symbol error probability (SEP)(More)
—We derive the symbol error probability for coherent detection of several types of-ary modulation schemes using maximal ratio combining. We consider Nakagami fading channels, where the instantaneous signal-to-noise ratios of the diversity branches are not necessarily independent or identically distributed. The proposed problem is made analytically tractable(More)
The focus of this paper is to derive the symbol error probability (SEP) of a Rake receiver with a limited number of fingers that track the strongest multipath components in a frequency-selective Rayleigh fading channel. We develop an analytical framework that allows the computation of the SEP for nonuniform power dispersion profiles (PDPs) and spreading(More)
