Abstract:
This work proposes a general equation for the channel reliability (L_c) of turbo code in DS/CDMA systems under flat fading channels and multiple access interference. The proposed reliability equation is suitable for prediction under low, medium as well high signal-noise ratio (SNR) operation system. The channel reliability equation was established as a function of system loading and SNR from fitting of Monte-Carlo simulation (MCS) performance results.
