“…The difference between the design of the receivers with memory and the hypothesis testing with memory is that the statistics corresponding to each signaling interval are statistically dependent in the receiver design problem whereas the experiments in the hypothesis testing problem are assumed to be independent. Baxa and Nolte [6] have considered the signal detection problem using Cover's approach. They discuss the problem under the constraint of finite soft memory.…”

A receiver is investigated with one-bit memory for communication channels with memory. The memory of the channel is characterized by the statistical correlation of the received bits due to fading. An optimal solution to the problem is considered but is found to be quite complex to implement. Therefore, a suboptimal receiver having a decision-feedback structure is examined. The performance of the receiver is shown to be better than a receiver without memory. Binary on-off keying system is considered as an example and numerical results are obtained.
