This a software runing on the matlab, it is used in the channel coding simulation. It include DVB-S2 LDPC, Covolution turbo, and block turbo code, You can choose which channel coding to run. it run the encoder and add white noise in the channel, then it run the decoder, and compute the error Rate.

The cable compensation system is an experiment system that performs simulations of partial or microgravity environments on earth. It is a highly nonlinear and complex system.In this paper, a network based on the theory of the Fuzzy Cerebellum Model Articulation Controller(FCMAC) is proposed to control this cable compensation system. In FCMAC ,without appropriate learning Rate, the control system based on FCMAC will become unstable or its convergence speed will become slow.In order to guarantee the convergence of tracking error, we present a new kind of optimization based on adaptive GA for selecting learning Rate.Furthermore, this approach is evaluated and its performance is discussed.The simulation results shows that performance of the FCMAC based the proposed method is stable and more effective.

提高卫星通信信道传输效率的新途径本 文 结 合 V SAT卫星通信系统设计中涉及卫星通信传输技术极为重要的 信道编码与调制解调方式，探讨了各种新型的卫星信道编码与调制解调技术， 它们的原理及在卫星通信中的应用。在数字调制中，信号传输质量主要取决于 比特差错率BER (Bit Error Rate)，因此要尽可能采用相同的每比特信号能量与 噪声功率谱密度比(Eb/N.)的条件下，BER低的调制方式，以节省卫星功率 另外频带利用率要尽可能的高，以节省宝贵的卫星频带。本文还对各种不同的 差错编码与调制技术进行了实验和详细的性能比较。

很多嵌入式系统，特别是应用于图像处理与高速数据采集等场合的嵌入式系统，都需要高速缓存大量的数据。DDR（Double Data Rate，双数据速率）SDRAM由于其速度快、容量大，而且价格便宜，因此能够很好地满足上述场合对大量数据缓存的需求。但DDR SDRAM的接口不能直接与现今的微处理器和DSP的存储器接口相连，需要在其间插入控制器实现微处理器或DSP对存储器的控制。

This code was used for making the practical measurements in section 2.3 of my thesis. This Matlab code allows an OFDM signal to be geneRated based on an input data file. The data can be random data, a grey scale image, a wave file, or any type of file. The geneRated OFDM signal is stored as a windows wave file, allowing it to be viewed, listened to and manipulated in other programs. The modified wave file can then be decoded by the receiver software to extract the original data. This code was developed for the experiments that I performed in my honours thesis, and thus has not been fully debugged. This is the original code developed for the thesis and so has several problems with it. The BER performance given by the simulations is infact Symbol Error Rate.

This m-file simulates MPSK (theoretical and simulated) with Gray coding This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit Rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).

SAM9261 BasicMMU Example code with ADS1.2 (163 kB) The goal of this project is to show how to use a PC100 SDRAM and the MMU to perform a rating with a 100MHz Bus Clock. The rating is based on Dhrystone 2.1. It shows the Rate when I+D Caches are disabled or enabled, with or without MMU and I Cache is disable or enabled, with or without MMU.
