Abstract :
This paper investigates high rate systematic punctured convolutional codes based on Forney´s (1970) results. High rate systematic punctured convolutional codes of rate-2/3 with constraint length 3⩽K⩽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 (BEPs) are also given
