Scalar Quantize-and-Forward for Symmetric Half-duplex Two-Way Relay Channels
Michael Heindlmaier, Onurcan Iscan, Christopher Rosanka
Scalar Quantize & Forward (QF) schemes are studied for the Two-Way Relay Channel. Different QF approaches are compared in terms of rates as well as relay and decoder complexity. A…
