Scarce-state-transition error-trellis decoding ofblock codes with BPSK signals

Abstract

A novel decoding technique for linear block codes with coherent BPSK signals is proposed. The new system has the same error performance as and similar complexity to the conventional trellis decoding of block codes. Like the scarce-state-transition Viterbi decoding of convolutional codes , the proposed system is also well suited for CMOS VLSI implementation and has a lower power consumption.
