摘要: In this paper, concatenated space-time codes applying iterative decoding topologies are investigated in wideband code division multiple access (WCDMA) communication systems. The coding operations based on the concatenation of a convolutional encoder, an interleaver, and employing multiple-transmitter/multiple-receiver diversity. As algorithm, (turbo) process is used, where priori probability exchanged between symbol-by-symbol decoder bit-by-bit decoder. Through optimum parameter selection considerable improvement error rate performance obtained. simulation results for multi-user forward link WCDMA system show that flat Rayleigh fading channel environment serially interleaved systems perform significant levels correction, additionally, applied configurations, it was observed nonrecursive outperforms recursive spacetime code.
