1. Strong interference:COFDM wireless transmitter is effectively against the multipath interference of signal waveform with the COFDM modulation. When the frequency selective fading occurs due to multipath transmission in the channel, only the subcarriers in the band depression and the signal carried by them are affected. The other subcarriers are not affected. Therefore, the overall bit error rate of the system is lower.
2. Anti-multipath fading: COFDM wireless audio video transmitter is effectively against the interference with the multi-carrier technique (COFDM). Compared to the single carrier, multi-carrier inherently resistant to time delay and has strong multipath capability. With joint coding of subcarriers & frequency diversity of the channel, the system’s performance is improved. Therefore, COFDM wireless system is suitable for multi-path environment and fading channel high-speed audio video data transmission.
