摘要
Communications systems operating over additive Gaussian noise channels with no feedback or ideal channel output feedback are now well studied. However, these set-ups model extreme cases and fail to provide much insight into more practical feedback systems. Therefore, in this paper, a noisy feedback communication system is considered. We study the application of linear multi-dimensional coding of the feedback and data signal. Upper bounds on the achievable rate for our set-up, that are functions of the open-loop capacity and ideal feedback capacity, are derived.
