Description: In this paper, we have proposed and investigated an
attractive joint source coding, channel coding, and modulation
(JSCM) scheme for a two-way relaying system. We commence by
quantifying the achievable capacity of the corresponding two-way
relay channel before proposing low-complexity source coding
schemes for concatenation with bandwidth- and power-efficient
coded modulation schemes. Extrinsic information transfer (EXIT)
charts are used to investigate the decoding convergence of the joint
source and channel decoder and for the overall system design. The
quality of the decoded source signals is quantified using the bit
error ratio (BER) metric. It is found that the two-way-relay-based
JSCM scheme is capable of attaining a combined coding and relaying gain of 5.7 dB over the conventional noncooperative JSCM
scheme when communicating over uncorrelated Rayleigh fading
channels in an outdoor environment
