Description: Simulations over AWGN and Rayleigh channels, at various signal-to-noise ratios, verify the excellent performance of this novel APEL-turbo scheme. Performance comparisons were carried out between turbo coded APEL, JPEG, and BMP image files.
To provide a fair comparison between the APEL and JPEG images, compression level had to be the same. This resulted in the data reduction for both APEL and JPEG to be around 5 to 1.
In the assessment of bit errors within a received image file, a quantitative pixel error rate offers a fairer comparison. Therefore, it is appropriate to represent the error performance in a ratio called “Pixel Error Rate (PER)”, which is a measure of the degree of image degradation.
Through the analysis of the ith received pixel’s variance from its transmitted value, a measure of visual disturbance, Δi, can be quantified as in (1), where ti and ri represent the transmitted and received pixel colours respectively, for an n colour image.

Description: Turbo decoder under awgn channel.
-The input is: uncoded bits,coded bits 1,coded bits2(interleaved), LLR from other source(if use only one turbo code ,fill all zero is ok), numbers of iterations, interleaver between two CC,
source bit,decoder id(if used in parreled connected turbo codes), interleaver between two sources(under the situation of two turbo codes).

Description: This script simulates the classical turbo encoding-decoding system.
It simulates parallel concatenated convolutional codes.
Two component rate 1/2 RSC (Recursive Systematic Convolutional) component encoders are assumed.
First encoder is terminated with tails bits. (Info + tail) bits are scrambled and passed to
the second encoder, while second encoder is left open without tail bits of itself.
Random information bits are modulated into +1/-1, and transmitted through a AWGN channel.
Interleavers are randomly generated for each frame.
Log-MAP algorithm without quantization or approximation is used.
By making use of ln(e^x+e^y) = max(x,y) + ln(1+e^(-abs(x-y))),
the Log-MAP can be simplified with a look-up table for the correction function.
If use approximation ln(e^x+e^y) = max(x,y), it becomes MAX-Log-MAP.- This script simulates the classical turbo encoding-decoding system.
