Abstract :
This paper proposes and investigates a tap selectable Viterbi equalizer for mobile radio communications. The proposed equalization algorithm can reduce the number of path metric calculations and the number of path selections in the Viterbi algorithm. Moreover, we propose an extended equalizer which has antenna diversity. This equalizer calculates the path metric using the antenna outputs and the results of channel estimators. Computer simulation is used to evaluate the BER performance of the proposed equalizer in a multipath radio channel
