TCM is the error correction coding and modulation of a combination of technology, coding and modulation processing as a whole at the same time, there are both error-correcting bandwidth compression capability, the basic principle is to use redundant signal sets to improve the correct wrong, thereby expanding the occupied frequency band is not the premise of increased coding gain. This can have the same transmission power and bandwidth while improving the reliability of digital transmission systems.
