Abstract :
This paper presents a discrete multitone transmission system employing turbo trellis coded modulation. The combination exploits the superior performance of turbo codes on additive white Gaussian noise channels. A single turbo code is used to modulate all subchannels in the multitone system. Thus, the turbo code is independent of the multitone system and channel parameters. The system can be used to achieve a significant coding gain or rate increase over an uncoded system.
