Abstract :
In this paper, we investigate a cross-layer framework in multiuser diversity system. Rate compatible Low-density Parity-check codes (LDPC) and space-time block codes (STBC) are employed. Under the assumption that the channel state information (CSI) is known at the receiver and the adaptive control signaling can be perfectly fed back to the transmitter, we first derive the expressions for the throughput of the system and then give the computer simulation results.
