Efficient Selection of Circular and Random Interleaver for Turbo Codes Multiuser CDMA System with Hadamard Spreading code in AWGN and Rayleigh Fading Channels

Journal of Engineering and Sustainable Development, 2012
Recently, turbo codes have attracted many researchers because of the codes astonishing performance at low signal to noise ratio SNR. The interleaver types and lengths is an important part in the design of a turbo code.

Three-Dimensional EXIT Chart Analysis of Iterative Detection Aided Coded Modulation Schemes

, 2006
The iterative convergence of iteratively detected coded modulation schemes having different block lengths, decoding complexity and an unequal error protection capability is studied, when communicating over AWGNchannels using 8PSK modulation.

Iterative Decoding of Turbo Product Codes (TPCs) Using the Chase-Pyndiah Turbo Decoder

, 2017
The ground breaking error correction codes that could achieve low bit error rates (near Shannon’s limit) were Turbo Codes (TCs) introduced by Berrou, Glavieux in 1993. The encoders for these outstanding codes were created by parallel concatenation of two recursive systematic convolutional codes separated by an interleaver.

Iterative channel estimation and decoding algorithm for quasi-coherent demodulation of Turbo coded GMSK signals

Tongxin xuebao, 2006
A new simple iterative channel estimation algorithm for quasi-coherent demodulation Turbo coded GMSK signals was presented. Based on the iterative decoding principle of Turbo code, the algorithm improved the channel esti- mation accuracy using output of ...
