Cognitive Radio Synchronization: A Survey

The timing synchronization has been a demanding scenario in orthogonal frequency division multiplexing (OFDM) and multiple input multiple outputs (MIMO).If it is used with Cognitive Radio (CR) then adaptive and intelligent has been adapted. The channel parameter helps to decide the communication synchronization. If the timing synchronization has been maintained then the signal deterioration may be less. Bit error rate (BER) is also reduced by proper synchronization. The main motivation behind this paper is to done the methodological survey to find the strategy for maintaining the synchronization timing jitter.
