Abstract :
OFDM (orthogonal frequency division multiplexing) is regarded as an excellent digital modulation method for various future digital broadcasting systems, including digital audio broadcasting (DAB). The scope of applications of the OFDM can be further expanded by combining it with TCM (trellis coded modulation). This TCM-OFDM system can transmit a much larger number of data than conventional OFDM, causing almost no degradation of bit error rate performance within the same frequency bandwidth. The concept of the TCM-OFDM system for terrestrial digital TV broadcasting and a system configuration that needs no carrier recovery at the receiver and gives simulation results of the bit error rate performances under various receiving conditions are described
