JOINT NETWORK-CHANNEL CODING WITH C-MRC BASED DEMODULATE AND FORWARD PROTOCOL IN TWO-WAY RELAY CHANNELS
Abstract
Research activities to reduce the system complexity and energy consumption of digital relaying based
cooperative wireless networks have yielded the demodulate-forward scheme where the relay performs
demodulation, instead of decoding, on the received signals. On the other hand, cooperative maximal ratio
combining (C-MRC) is another high-performance low-complexity technique used to combat error propagation
in digital relaying without exploiting CRC codes which decreases the transmission efficiency. In this study, we
propose a C-MRC based demodulate and forward protocol for two-way relay channels where two users
exchange information via a relay. The transmission is divided into three phases in time where the first and
second phases are allocated to the transmissions of uncoded or convolutionally encoded data of the users. After
demodulation, the relay broadcasts the bit-wise XOR-ed packet to the users in the third phase. The numerical
results for Rayleigh fading show that the proposed approach provides full diversity gain.
