Error probability bounds for systematic convolutional codes
Edward A. Bucher, J. A. Heller · IEEE Transactions on Information Theory · 1970
Upper and lower bounds on error probability for systematic convolutional codes are obtained. These bounds show that the probability of error for a systematic convolutional code is larger than the probability of error for a nonsystematic convolutional code of the same encoder-shift-register length. Two different interpretations of these results are given.
