Description: Abstruct- We describe novel interleaver and deinterleaver
architectures that support bandwidth efficient memory access for
decoders of turbo-like codes that are used in conjunction with
high order modulations. The presentation focuses on a decoder
for serially concatenated pulse-position modulation (SCPPM),
which is a forward-error-correction code designed by NASA to
support laser communications from Mars at more than 50 megabits-
per-second (Mbps). For 64-ary PPM, the new architectures
effectively triple the fan-in of the interleaver and fan-out of the
deinterleaver, enabling parallelization that doubles the overall
throughput. The techniques described here can be readily modified
for other PPM orders.

Description: urbo码是1993年法国人Berrou提出的一种新型编码方法。它巧妙的将卷积码和随机交织器结合在一起；同时，采用软输出迭代译码来逼近最大似然译码-urbo code is 1993 French Berrou proposed a new encoding method. It is clever to convolutional codes and random interleaver together the same time, the use of soft-output iterative decoding to approximate the maximum likelihood decoding

Description: 使用C编写的基于QPP交织器的turbo编码及译码器。编码器出来的结果没有经过调制直接通过高斯白噪声信道（加入随机噪声），译码后的结果与编码前结果相同。开发环境是visual studio2010.-Written in C, based on QPP interleaver turbo encoder and decoder. Out the results of the encoder is not modulated directly by a white Gaussian noise channel (adding random noise), the decoded result is the same as the pre-encoding results. The development environment is visual studio2010.

Description: Turbo 码的matlab程序。它巧妙地将两个简单分量码通过伪随机交织器并行级联来构造具有伪随机特性的长码，并通过在两个软入/软出(SISO)译码器之间进行多次迭代实现了伪随机译码。他的性能远远超过了其他的编码方式，得到了广泛的关注和发展，并对当今的编码理论和研究方法产生了深远的影响，信道编码学也随之进入了一个新的阶段 -Turbo code matlab program. It skilfully two simple component codes through pseudo-random interleaver parallel concatenated to construct the long code of a pseudo-random characteristics, and through multiple iterations between the two soft in/soft-output (SISO) decoder a pseudo-random decoding.
