Abstract :
I-Q TCM is a form of coded modulation in which two independent encoders select the in-phase and quadrature components of the transmitted signal. This design approach results in a significant increase in the minimum time diversity when compared with comparable “traditional” TCM schemes. I-Q TCM schemes of varying complexity are presented; it is shown that the coding gains of moderately complex systems are very close to what is expected from the cutoff rate limit
