Abstract

In this paper, we study the coded modulation schemes for pre-transformed (PT) Orthogonal Frequency Division Multiplexing (OFDM) systems, in short PT-OFDM systems. For quasi-static fading channels, we show that the signal to noise ratio (SNR) for different elements in a PT block is constant due to the spreading property of the PT matrix. Based on this observation, we propose trellis coded modulation (TCM) as the better coded modulation scheme for PT-OFDM system compared to bit interleaved coded modulation (BICM). This is further verified by a the BER comparison of coded PT-OFDM systems using different coded modulation schemes through computer simulations.
