Abstract

A method and system for transmitting signals using unequal error protection (UEP). According to the method, symbols having a higher level of coding protection are detected and decoded first, soft reliability information is generated, and then the previously detected symbols and soft reliability information are used to detect and decode symbols having the next lower level of coding protection. The symbols having lower levels of coding protection benefit from the decoding of all previous classes of symbols. Data symbols can be interleaved to further enhance system performance.
