Abstract :
A novel scarce-state-transition (SST) type trellis decoding system for (n,n-1) convolutional codes with coherent BPSK signals is proposed. The new system retains the same number of binary comparisons as the syndrome-former trellis decoding technique. Like the original SST-type encoder trellis technique, the proposed system is also suitable for CMOS VLSI implementation. A combination of the two techniques results in a less complex and low power consumption decoding system
