Multilevel Coding for the Full-Duplex Decode-Compress-Forward Relay Channel
Abstract: The Decode-Compress-Forward (DCF) is a generalization of Decode-Forward (DF) and Compress-Forward (CF). This paper investigates conditions under which DCF offers gains over DF and CF, addresses the problem of coded modulation for DCF, and evaluates the performance of DCF coded modulation implemented via low-density parity-check (LDPC) codes and polar codes. We begin by revisiting the ...
متن کاملPractical Partial Decode and Forward Encoding Scheme for Relay Channel
In this paper, a source-destination pair, which is augmented by a half-duplex relay, is considered. Two practical partial decode and forward encoding schemes are proposed. In these transmission schemes, the relay may decode the source's signal either partially or completely. In each encoding technique, twophase transmission scheme is developed in which the relay can partially listen to the sour...
متن کاملOptimum Power Allocations for Fading Decode-and-Forward Relay Channel
Abstract—In this paper optimum power allocations are derived for a fading decode-and-forward full-duplex relay channel, analytically. Individual power constraints for the source and the relay are assumed and the related optimization problem is analyzed for two scenarios. First, optimization is taken over the source power, the relay power, and the correlation coefficient between the transmitte...
متن کاملDesign of Nested LDGM-LDPC Codes for Compress-and-Forward in Relay Channel
A three terminal relay system with binary erasure channel (BEC) was considered, in which a source forwarded information to a destination with a relay’s ”assistance”. The nested LDGM (Low-density generator-matrix) -LDPC (lowdensity parity-check) was designed to realize Compress-andforward (CF) at the relay. LDGM coding compressed the received signals losslessly and LDPC realized the binning for ...
متن کاملSpatially Coupled Protograph-Based LDPC Codes for Decode-and-Forward in Erasure Relay Channel
We consider spatially-coupled protograph-based LDPC codes for the three terminal erasure relay channel. It is observed that BP threshold value, the maximal erasure probability of the channel for which decoding error probability converges to zero, of spatially-coupled codes, in particular spatially-coupled MacKay-Neal code, is close to the theoretical limit for the relay channel. Empirical resul...
