Abstract :
New block coded 8-PSK modulations with unequal error protection (UEP) capabilities for Rayleigh fading channels are presented. The proposed codes are based on the multilevel construction of Imai and Hirakawa (1977). It is shown that the use of linear UEP (LUEP) codes as component codes in one or more of the encoding levels provides increased error performance with respect to conventional multilevel codes
