要約(日本語): In previous works, we proposed a serial unequal error protection (UEP) code system for use with information sources that contain a mixture of both important and less important data. Also, theoretical analyses of the 2RING signal constellations and TCM codes are presented, and the effectiveness and the validity of the system for additive white Gaussian noise (AWGN) channels are confirmed.
In this paper, a decision feedback equalizer with an Adaptive Error Prediction Filter (AEPF-DFE) is proposed to combat frequency selective fading. The effectiveness of the AEPF-DFE alone and the AEPF-DFE in the proposed UEP system in frequency selective Rayleigh fading channels is shown using computer simulations.
