A code-aided adaptive equalizer using soft decision-directed algorithm and convolutional coding for fading channels

Abstract: We propose to use a soft decision-directed least mean square algorithm in a code-aided equalizer for fading channels. The soft-output Viterbi algorithm is used in decoding the convolutional ...
