Relaying in non-ideal conditions
Yunfei Chen · Institution of Engineering and Technology eBooks · 2016
Wireless relaying has been proposed as a promising technology to achieve either diversity gain via a distributed multiple-input multiple-output setting or extended network coverage without the need for extra infrastructure. In practice, this is often performed under non-ideal channel and signal conditions. In this chapter, the effects of various non-ideal conditions on the performance of wireless relaying will be examined. We focus on amplify-and-forward (AF) relaying, where the relay node amplifies and forwards the signal received from the source node to the destination node without any decoding. The examined non-ideal conditions include feedback delay, link correlation, non-Gaussian interference, and wireless power.
