Performance Analysis of Pilot-Aided Forward CDMA Cellular Channel

Abstract

In this thesis we analyze the performance of the forward channel of a DS-CDMA cellular system operating in a Rayleigh-fading, Lognormal-shadowing environment. We develop an upper bound on the probability of bit error, including all the participating interference. In addition, various techniques such as sectoring and forward error correction in the terms of convolutional encoding are applied to optimize the performance. We further improve the performance by applying a narrow bandpass filter in the pilot tone branch of the demodulator. We then adjust the bandwidth of the filter in the means of the interference power passing through and observe the effects on the probability of bit error of the system. Moreover, pilot tone power control is added to enhance the demodulation. Finally, in this thesis a simple single cell system functioning as a port-to-port network communication between very small numbers of users is analyzed.
