The Effect of Channel Coding Rate on the Resistance of Direct-Sequence Spread-Spectrum Communication Systems to Narrow-Band Interference

Progress In Electromagnetics Research B, Vol. 7, 89-103, 2008
Abstract
In this paper, optimum code rates for a number of channel codes which are used in the coded direct-sequence spread-spectrum (DS-SS) and coded code-division multiple-access (CDMA) communication systems operating in the presence of narrow-band interference (NBI) are investigated. The criteria in obtaining the optimum code rates is based on maximum tolerable NBI power to signal power ratio. First, we consider Optimum Codes, Super Orthogonal Codes (SOC), and Repetition Codes for a single-user DS-SS system and then, the optimum rates for the Optimum Codes in CDMA system using single-user and multi-user detection methods are obtained. In the latter case, we will consider evaluating the optimum code rate for two different multi-user detection schemes, namely, a detection method using joint coding/decoding and a detection method using successive interference cancellation.
