[Communication] turbodecode

Description: 第一个编码的程序调出来了，1/2的码率，用的是8×8行列交织器，rsc用的是 g0=[1 1 1]，g1=[1 0 1]。算法是根据网格图来编写的。信息输入是64bit的（0，1，0，1，0，1，0，1，0，0，、、、、、），最后结果是stream[128]＝[00100110011000100101000001010101000001010101000001000101000101000101000101000101000001000100000001000100000001010100000101011011] 第二个译码程序用的是sova译码算法，迭代次数选的6，现在解码出来的信息是对的，和原输入编码器的信息位一致。然后我有意把译码器输入stream序列打错几个bit都能正确译码。-err

[Streaming Mpeg4] H264AVCDecoderLibTestStatic

Description: Simulation of Turbo Encoding and Decoding" A randomly generated information bits are encoded with Turbo Encoder (which uses two RSC Encoders in parallel along with an interleaver) and added with AWG Noise then decoded with Turbo Decoder (Soft Output Viterbi Algorithm). We have understood/used TI TMS320C55x Processor and its assembly instruction set.

[3G develop] turbo_sys_demo

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. It simulates parallel concatenated convolutional codes.
