In this chapter, 16-ary QAM symbols are referred to as frequency domain symbols and their N-point IFFT is referred to as an OFDM symbol. Our results indicate that combining iterative frequency offset estimation with iterative demodulation and decoding reduces the bit error rate with respect to the SNR. Weighting the reconstructed samples using (19) prevents error propagation when a large number of the decoded bits and reconstructed symbols are in error.
