摘要：Unitary space-time modulation (USTM) is idealiy suited for time independent rapid fading channels because it can work well without channel state information (CSI). In reality the fading coefficients are always correlated, in which condition differential unitary space-time modulation (DUSTM) was proposed. However, it also meets with the too high bit error rate (BER) problem when the signal-to-noise ratio (SNR). In this paper, we propose a DUST symbol-based turbo code and its corresponding MAP decoding algorithm which can decrease the BER for a large scale and give a good transmit diversity performance. Compared with bit wise processing scheme, it can greatly reduce the calculation complexity and storage account and perform well at the same time.
