COFDM Transmitter Overview

The HC-T820 COFDM transmitter module combines COFDM modulation with H.265/H.264 encoding for low-latency video/audio transmission in high-speed and NLOS conditions. The modular design features separate video codec encoder and COFDM modulator boards connected via flat cable, plus a transparent UART transmission channel.
