A Simplification of the Modified Bahl Decoding Algorithm for Systematic Convolutional Codes

Abstract

this paper we present a simplified APP algorithm which was successfully tested using the rate half systematic convolutional 16 state Turbo code given in [2], with a 20#20 block interleaver of 400 bits. For an E b /N 0 = 2.0 dB and eight iterations, an output bit error ratio P b # 1.5 # 10
