In this contribution the transmission of M-PSK and M-QAM modulated orthogonal frequency division multiplexed (OFDM) signals over an additive white Gaussian noise (AWGN) channel is considered. The degradation of the bit error rate (BER), caused by the presence of carrier frequency offset and carrier phase noise is analytically evaluated. It is shown that for a given BER degradation, the values of the frequency offset and the linewidth of the carrier generator that are allowed for OFDM are orders of magnitude smaller than for single carrier systems carrying the same bit rate. >read more

TL;DR: This paper derives the best data-pilot-multiplexed scheme in terms of minimizing data-interference on pilot tones and gives a correlated data insertion scheme (CD) and a null data insertion Scheme (ND) (no data are transmitted on the left and right adjacent tones of each pilot).
