摘要

为了在未知频率选择信道上实现可靠的传输，提出了一种新的空时(ST)收发方案。该方案的新颖之处在于在传输的符号帧中构建了一个独特的圆形结构，以便(i)使用代数处理可以减轻符号间干扰(ISI)的影响，(ii)可以实现对所提议的信号帧的检测的优越性能。这种新型的低复杂度收发器是基于循环群码和非相干接收的。它能够在时间色散多输入多输出(MIMO)信道状态信息(CSI)不可用时进行可靠检测，并适应时变信道。

A differential space-time transceiver for unknown time-dispersive multipath channels

This paper introduces a new space-time (ST) transceiver scheme for the reliable transmissions over the unknown frequency selective channels. The novelty of this scheme is in building into the transmitted symbol frame a unique circular structure so that (i) the inter-symbol-interference (ISI) effects could be mitigated using the algebraic processing and (ii) superior performance in the detection of the proposed signaling frame could be achieved. The new and low complexity transceiver is based on cyclic group codes and a non-coherent reception. It enables reliable detection when the time dispersive multiple input multiple output (MIMO) channel state information (CSI) is not available and it accommodates time varying channels.
