Abstract :
The authors discuss the microelectronic realization of a Viterbi equalizer with soft decision outputs (SOVE, soft output Viterbi equalizer) using XILINX XC4000 series logic cell arrays (LCAs), a special type of field programmable gate array. LCAs are chosen because of their high flexibility and their low price. They are well suited for prototyping. The most advantageous features of the presented SOVE are real-valued signal processing in the intermediate frequency domain and flexibility due to the calculation of the metric increments by using ROM look-up tables
