Turbo code channel reliability for DS/CDMA systems under slow and frequency selective fading and multiple access interference.

This work analyzes the Turbo and Convolutional codes strategies applied to the single-user detection (SuD) problem in multiple access systems DS/CDMA, in multipath slow Rayleigh channels. In this work, a new equation for the DS/CDMA channel reliability, obtained from Monte Carlo Simulations (MCS), i...

Description
Summary:This work analyzes the Turbo and Convolutional codes strategies applied to the single-user detection (SuD) problem in multiple access systems DS/CDMA, in multipath slow Rayleigh channels. In this work, a new equation for the DS/CDMA channel reliability, obtained from Monte Carlo Simulations (MCS), is proposed. Comparison with the literature results and has indicated a superior performance in the high Eb/N0 regions; in other Eb/N0 regions the proposed equation has similar performance than those described in the literature. Additionally, this work makes an analysis of the complexity/memory requirements versus performance of DS/CDMA receivers considering turbo (CDMA2000) and Viterbi (IS-95) decoders.
