TRELLIS CODED MODULATION WITH UNEQUAL ERROR PROTECTION

摘要

A method and system (500) of transmitting data separates data bits into a first bit set and a second bit set; and maps the first and second bit sets to a symbol constellation, where an Euclidian distance in the symbol constellation between values for the bits in the first bit set is less than an Euclidian distance in the symbol constellation between values for the bits in the second bit set, and wherein within each of the first and second bit sets, the bits are mapped to the symbol constellation using trellis-coded modulation (520, 525).
