چکیده
In this paper we analyze the performance in terms of Bit Error Rate (BER) and Frame Error Rate (FER) of a multi-binary turbo coded system over Rayleigh flat fading multipaths channels. The turbo codes (TCs) proposed here calls for the parallel concatenation of two identical rate r/(r+1) recursive systematic convolutional RSC codes. It results rate r/(r+2) Multi-Binary Turbo Code (MBTC). Data block length has k=m⋅N=2⋅752 bits. The interleavers presented in 2005 by C. Douillard and C. Berrou are used. The results are illustrated with two examples based on double-binary (r=2) 8-state and 16state TCs, for (6 7 1 5) RSC codes and (11 11 1 12) RSC codes. QPSK modulation is employed.

Multy Binary Turbo Coded Wofdm Performance in Flat Rayleigh Fading Channels
In this paper, the application of Multi Binary Turbo Codes (MBTCs) to two multicarrier modulation techniques used for transmission in the flat radio fading channel is studied. Thus, the performance of the coded versions of Orthogonal Frequency Division Multiplexing (OFDM) and of its wavelets based version (WOFDM) is evaluated under several simulation scenarios. These scenarios take into account...

متن کاملPerformance of Turbo Codes with Max-Log-MAP Decoding on Rayleigh Fading Channels
In this paper we investigate performance of turbo codes with Max-Log-MAP decoding on slow, flat Rayleigh fading channels. In order to simplify decoding algorithm implementation for a fading channel, the Gaussian distribution is applied to a channel metric. By means of computer simulations, we estimate BER of turbo codes on fully-interleaved and correlated channels with ideal CSI and without CSI...

The received signal from (radio) Rice flat fading transmission channels has both unfading (like in the AWGN –Additive White Gaussian Noise channel) and fading components (like in the Rayleigh channel).

Abstract— This paper addresses the design and performance evaluation with respect to capacity of M-PSK turbo-coded systems operating in frequency-flat, time-selective Rayleigh fading. The receiver jointly performs channel estimation and turbo decoding, allowing the two processes to benefit from each other. To this end, we introduce a suitable Markov model with a finite number of states, designe...
