Abstract

In this paper, the applicability of 32 trellis-coded OFDM waveform is studied for the tactical information communications system in NCW (Network Centric Warfare). In order to reduce received SNR in BER 1.0E-6 conditions, we proposed a 32-TCM. We also applied OFDM technologies such as timing recovery, carrier recovery, and equalizer, in order to reduce robust channel impairments caused by non-LOS environments where a signal is not received from another system. Simulation results show that coding gain of a 32 trellis-coded OFDM waveform has about 7 dB and 2 dB, compared to single-carrier 16-QAM waveform and OFDM (16QAM) waveform in tactical communication environments, respectively.
