Separately turbo-coded space-time coding with QPSK and its decoding scheme

摘要

In this paper, we propose separately turbo-coded space-time coding scheme that uses some turbo encoders as an component encoder. And its decoding scheme employs the decoded information of the other component decoder corresponding to the component encoder as channel interference information with multiple antenna diversity. For computer simulation results, the BER performance of proposed coding and decoding scheme improved about 2 [dB] at BER of 10{sup}(-5) compared with the decoding method without using the other decoded information on fast Rayleigh fading channel. And the BER performance of proposed scheme improved about 8 [dB] at BER of 10{sup}(-4) with quasi-static Rayleigh fading channel.
