Convolutional codes are preferred types of error control codes which can achieve low BERs at signal to noise ratio (SNR) very close to Shannon limit. Here, a new method of convolutional encoding is proposed using the general Booth algorithm for multiplication. This algorithm follows a fast multiplication process and achieves a significantly less computational complexity over its conventional counterparts. It can be a useful technique for use in chip design as it provides significant improvements. In this work, the performance of conventional convolutional coding with Viterbi decoding in AWGN channel, is studied and the results show the effectiveness of the work described here.
