摘要：

This paper investigates high rate systematic punctured convolutional codes based on Forney's results, High rate systematic punctured convolutional codes of rate-2/3 with constraint length 3 less than or equal to K less than or equal to 7 and rate-3/4 through 15/16 with K = 7 are derived using the rate-1/2 best known nonsystematic convolutional codes, Weight spectra of newly discovered systematic punctured convolutional codes are provided and compared with the best known nonsystematic punctured codes, Simulation results on bit-error probabilities (BEP's) are also given.
