Timing and Carrier Synchronization With Channel Estimation in Multi-Relay Cooperative Networks

Multiple distributed nodes in cooperative networks generally are subject to multiple carrier frequency offsets (MCFOs) and multiple timing offsets (MTOs), which result in time varying channels and erroneous decoding. This paper seeks to develop estimation and detection algorithms that enable coopera...
