Scalar and Vector Compress and Forward for the Two Way Relay Channels
Di Chen, Volker Kuehn · 2016
Both scalar and vector quantization are studied when Compress and Forward (CF) is performed in the Two Way Relay Channels. The optimization schemes of these two kinds of quantizers aiming to maximize the sum rate are proposed. The optimization schemes are a combination of the Information Bottleneck (IB) method and the Bi- Section method. The performance of these two types of quantizers are compared. Then we compare the optimized CF with other relaying schemes, i.e., Decode and Forward (DF) and optimized Quantize and Forward (QF).
