More Information
Summary:Coded orthogonal frequency division multiplexing (COFDM) is a robust technique in fading environments. In this paper, higher modulation schemes are considered with OFDM for a Rician fading channel. Here, convolutional coding (CC) and trellis coded modulation (TCM) are combined with OFDM. Bit error rate (BER) performances are analyzed with L and Ka frequency bands. Trellis coded OFDM (TCM-OFDM) gives a better performance compared to convolutional coded OFDM (CC-OFDM) with a lower trellis complexity. And also the performance does not depend significantly on the frequency band.
