An Efficient Viterbi Decoder for Digital Mobile Multimedia Broadcasting Receiver

In the design of Viterbi Decoder of punctured convolutional codes, the SST method is used to reduce power consumption in this paper. Moreover, the punctured vector table is optimized by hard wire logic, thus reducing the area required by the system. Effective operation of adjustment is used to reduce the word length of path metric memory. At the same time, this algorithm can also help reduce operation load by controlling the highest order of path metric memory, thereby reducing the scale of hardware.
