ABSTRACT:
A cable transmission system transmits television signals in a family of M-level symbol data constellations. Lower frequency ones of the television signals are transmitted in data constellations of relatively higher values of M and higher frequency ones of the television signals are transmitted in data constellations of relatively lower values of M to optimize signal to noise performance and spectrum utilization.
