Incremental relaying protocols for extended LDPC coded cooperative diversity

Cooperative diversity achieves the diversity gain without adding physical antennas to the users or mobile stations. Coded cooperative diversity improves the frame-error-rate (FER) performance. The throughput of coded cooperative diversity can be enhanced by incremental relaying protocols which utilize limited feedback from the destination. In this work, we present two feedback-based protocols for extended low-density parity-check (LDPC) coded cooperative diversity framework.
