Performance Comparison of Punctured Turbo Codes and Multi Binary Turbo Codes

In this paper we analyze the performance of punctured turbo codes (TCs) and punctured multi binary turbo codes (MBTCs) over additive white Gaussian noise (AWGN) channel in terms of Bit Error Rate (BER) and Frame Error Rate (FER). We consider the original TCs that consist of the parallel concatenation of two identical rate 1/2 recursive systematic convolutional (RSC) codes. We also consider MBTCs that consist of the parallel concatenation of two identical rate 2/3 RSC codes. In order to achieve high spectral efficiency, we focus on codes with higher coding rates, i.e., rates 1/2, 3/5 and 2/3 for both TCs and MBTCs by using puncturing operations. For sake of compatibility with standards IEEE 802.1 In and DVD-T, we consider only codes with moderate data block length, i.e., 1504 bits in all cases. The results are illustrated with examples based binary and duobinary 16-state TCs.
