Exact Analysis of PCC-OFDM Subjected to Carrier Frequency Offset over Nakagami-m Fading Channel

Orthogonal frequency division multiplexing (OFDM) is sensitive to frequency synchronization errors which results in degradation of system performance. Polynomial cancelation coding (PCC) OFDM is introduced to reduce OFDM sensitivity to carrier frequency offset. In this paper, PCC-OFDM performance modeling is considered. An exact closed form expression for symbol error rate (SER) is evaluated for PCC-OFDM subjected to carrier frequency offset. The performance is evaluated over Nakagami-m fading channel. PCC-OFDM improvement as compared to conventional OFDM is emphasized. It is shown that PCC-OFDM outperforms conventional OFDM by about 4 dB in the QPSK modulation at error rate of 10-2 over fading channels with a normalized carrier frequency offset of 0.1.
