Abstract

The construction of block multidimensional M-PSK modulation codes with unequal error protection (UEP) is considered. An UEP profile for the Rayleigh fading channel is obtained by partitioning fourdimensional constellations that are Cartesian products of non-uniform 8-PSK modulations or are subsets of a product of uniform modulations. New codes are constructed by using the multilevel coding technique with very simple binary component codes. These codes are matched to the vector-sum excited linear predictive (VSELP) codec described in the IS-54 mobile system. .One of the constructed codes has four levels of protection and achieves a coding gain of 16.0 dB (at a SEGSNR of 2.0 dB) in comparison with a system that employs uncoded 4-PSK modulation.
