Joint signal‐to‐noise ratio‐based transceiver design for amplify‐and‐forward multiple‐input multiple‐output relay systems

Semi‐blind parallel factor based receiver for joint symbol and channel estimation in amplify‐and‐forward multiple‐input multiple‐output relay systems

“…Moreover, when the concept of relay systems is combined with that of multiple‐input multiple‐output (MIMO) technology, the system performance can be further enhanced by using the spatial dimension [3, 4]. Recently, the amplify‐and‐forward (AF) relay has attracted significant interest in the MIMO relay systems because of its simplicity of implementation, especially when complexity and latency issues are of importance [5–7].…”
