Uniform Quantization for Multi-Antenna Amplify–Quantize–Forward Relay

open access: yesIEEE Access
In this paper, we investigate a multi-antenna amplify-quantize–forward (AQF) relay system, where a half-duplex relay quantizes both the real and imaginary components of amplified received signals, storing them in memory before forwarding them to a
