| Abstract(in English) | When the transmitter maps a bit-interleaved coded sequence into DPSK symbols, turbo (iterative) decoding is applicable at the receiver by regarding a differential encoder in DPSK as an inner encoder, i.e., serial concatenation of two encoders. In this paper, we examine blind iterative decoding in a bit-interleaved coded DPSK system. We also propose a blind channel estimation scheme based on decision feedback because coherent detection is required for the iterative decoding. The result obtained by computer simulations shows that performance of the iterative decoding significantly outperforms that of coherent PSK with perfect CSI. In addition, it is demonstrated that the proposed channel estimation scheme provides the performance approaching to that of the perfect CSI case by 0.1dB and 0.9dB in no fading and dynamic fading environments, respectively, at BLER of 10^<-2>. |
