摘要

均衡后组合与信道估计(EPCCE)最近被提出用于空时分组编码在频率选择性衰落信道中的应用。尽管EPCCE提供了完整的分集，但由于信道估计不完美，它的性能可能会下降。为了在训练符号数量有限的情况下提高信道估计和接收机的性能，提出了一种基于决策反馈均衡和基于天线间干扰消除的迭代信道估计的EPCCE接收机。

Space-time block coding using decision feedback equalization and iterative channel estimation with inter-antenna interference cancellation

Equalization post-combining with channel estimation (EPCCE) has recently been presented for applications with space-time block coding in frequency selective fading channels. In spite of offering full diversity, EPCCE can suffer from performance degradation due to imperfect channel estimate. We propose a new EPCCE receiver using decision feedback equalization (DFE) and iterative channel estimation based on inter-antenna interference cancellation in order to improve the channel estimate and the performance of the receiver when the number of training symbols is limited.
