Enhanced ZP-OFDM receiver in multi-relay cooperative networks
Homa Eghbali, Sami Muhaidat, Ibrahim Y. Abualhaol · 2012
Sub-optimal Zero-Padding Orthogonal Frequency Division Multiplexing (ZP-OFDM) receivers have been developed in the literature to trade-off performance with complexity. In this paper, we propose a novel cooperative low-complexity minimum mean square error (LC MMSE)-ZP-OFDM receiver that is able to bring complexity reduction in the receiver design, while outperforming conventional cooperative MMSE-ZP-OFDM.
