Performance Analysis of Viterbi Detection of Class IV Partial Response for Data Transmission Over Multipair Cables

Partial response class IV signaling combined with Viterbi decoding to perform maximum-likelihood sequence detection is considered for high-speed data transmission over twisted-pair cables. In order to establish which data rates and distances can be achieved by this method, performance evaluation is conducted. Binary and quaternary modulations are considered, and disturbance of the received signal by near-end and far-end crosstalk and additive white Gaussian noise is taken into account. A benchmark comparison with rigorously optimized symbol-by-symbol detection systems employing AMI and HDB3 line coding is presented. © 1991 IEEE
