A receiver of communication system for orthogonal frequency division multiplexing and Method for mitigate a phase noise in thereof

摘要

The present invention , unlike the conventional receiver using a pilot symbol to mitigate the phase noise , that is received by estimating and compensating the phase noise from the OFDM symbol , to a receiving apparatus and its phase noise mitigation method in an OFDM communication system which can improve the transmission efficiency and the error rate performance of the OFDM system . ;
