Joint channel, phase noise, and carrier frequency offset estimation in cooperative OFDM systems

Salim, Omar Hazim; Nasir, Ali; Xiang, Wei; Kennedy, Rodney


Cooperative communication systems employ cooperation among nodes in a wireless network to increase data throughput and robustness to signal fading. However, such advantages are only possible if there exist perfect synchronization among all nodes. Impairments like channel multipath, time varying phase noise (PHN) and carrier frequency offset (CFO) result in the loss of synchronization and diversity performance of cooperative communication systems. Joint estimation of these multiple impairments...[Show more]
