Influence of Trellis Termination Methods on Turbo Codes Performances over Middleton Class-a Channels

چکیده
Turbo codes occupy a special place in the field of wireless communications for their outstanding performances in correcting errors that appear on transmission channels. This paper analyzes the influence of trellis termination methods on turbo codes performances, over a channel affected by impulsive noise and Binary Phase-Shift Keying modulation. The statistical model used for the impulsive noise is Middleton Class-A. The evaluation of turbo code performances was done in terms of bit error rate (BER) and frame error rate (FER), for two lengths of S-random interleaver. The simulations were performed for different values of the parameters that describe the impulsive noise model. The used decoding algorithm is Max-Log-MAP.

On the theory and performance of trellis termination methods for turbo codes
The performance of a Turbo code can be severely degraded if no trellis termination is employed. This paper investigates the implications of the choice of trellis termination method for Turbo codes, and explains the origin of the performance degradation often experienced without trellis termination. An efficient method to derive the distance spectrum of Turbo codes for different trellis terminat...

This paper makes a comparison in terms of the bit error rate (BER) and frame error rate (FER) versus signal to noise ratio (SNR) between the different methods of the trellis termination of the recursive, systematic, single and double-binary convolutional codes used in turbo-codes. The best four well known termination methods were investigated: circular (tailbiting), single-termination, interlea...

In this paper we present a modification of a typical turbo code allowing for adaptive changing of the code rate and signal synchronization properties. The proposed algorithm inserts pilot symbols into the code structure and frequently terminates the first trellis of the turbo encoder by inserting tail bits into the data sequence. By changing the length of the number of bits between the terminat...
