Performance of Parallel Concatenated Convolutional Codes (PCCC) with BPSK in Nakagami Multipath M-Fading Channel

Abstract

In this paper the encoder design of two parallel concatenated convolutional codes (PCCC) have been introduced. Concept of puncturing is also considered. PCCC is also named as Turbo codes. Decoding process of turbo-codes using a maximum a posteriori (MAP) algorithm has been discussed. Different parameters affect the BER performance of turbo codes are introduced .The previous studies focusing on the turbo-codes performance in (AWGN) and Rayleigh multipath- fading channels. The real importance of Nakagami –m fading model lies in the fact that it can often be used to fit the indoor channel measurements for digital cellular systems such as global system mobile (GSM). In this paper, the BER performance and comparative study of turbo-codes in Nakagami multipath- fading channel is verified using Matlab simulation program.
