符号干扰信道的一个新比特差错概率界

A New Bit Error Probability Bound for Intersymbol Interference Channels

本文研究了在白高斯噪声干扰下,符号干扰(ISI)信道的最大似然序列检测(MLSD)技术。导出了一个新的比特差错概率上界,其界紧于Forney界。证明了在符号干扰无限严重时,由符号干扰所造成的性能损失,对任何物理信道将逐渐减小为零。

Maximum likelihood sequence detection (MLSD) of digital signaling subject to intersymbol interference (ISI) and additive white Gaussian noise (AWGN) is considered. A new and simple bit error probability bound is obtained, especially for the low and high SNR regions. In addition, in the case of infinite-length ISI, the performance loss due to the ISI tends to zero for physical channels.
