This paper proposes an algorithm that distributes bits according to different noise margin levels, thereby realizing unequal error protection (UEP). The new approach is based on a non-UEP allocation algorithm by Chow, Cioffi, and Bingham. The new algorithm is designed to be robust to non-stationary impulse noise and channel variations by integrating a new SNR-sorting scheme. Simulation results show that the highly protected bits are spread over a high number of carriers at low SNR, thereby… CONTINUE READING
