Low-Complexity LDPC Codes with Near-Optimum Performance over the BEC
Recent works showed how low-density parity-check (LDPC) erasure correcting codes, under maximum likelihood (ML) decoding, are capable of tightly approaching the performance of an i...

Power-controlled feedback and training for two-way MIMO channels
Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...

Optimal and Suboptimal Power Allocation Schemes for OFDM-based Cognitive Radio Systems
In this paper, we investigate an optimal power loading algorithm for an OFDM-based cognitive radio (CR) system. The downlink transmission capacity of the CR user is thereby maximiz...
