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.

提高衛(wèi)星通信信道傳輸效率的新途徑本 文 結(jié) 合 V SAT衛(wèi)星通信系統(tǒng)設(shè)計(jì)中涉及衛(wèi)星通信傳輸技術(shù)極為重要的 信道編碼與調(diào)制解調(diào)方式，探討了各種新型的衛(wèi)星信道編碼與調(diào)制解調(diào)技術(shù)， 它們的原理及在衛(wèi)星通信中的應(yīng)用。在數(shù)字調(diào)制中，信號(hào)傳輸質(zhì)量主要取決于 比特差錯(cuò)率BER (Bit Error rate)，因此要盡可能采用相同的每比特信號(hào)能量與 噪聲功率譜密度比(Eb/N.)的條件下，BER低的調(diào)制方式，以節(jié)省衛(wèi)星功率 另外頻帶利用率要盡可能的高，以節(jié)省寶貴的衛(wèi)星頻帶。本文還對(duì)各種不同的 差錯(cuò)編碼與調(diào)制技術(shù)進(jìn)行了實(shí)驗(yàn)和詳細(xì)的性能比較。

很多嵌入式系統(tǒng)，特別是應(yīng)用于圖像處理與高速數(shù)據(jù)采集等場合的嵌入式系統(tǒng)，都需要高速緩存大量的數(shù)據(jù)。DDR（Double Data rate，雙數(shù)據(jù)速率）SDRAM由于其速度快、容量大，而且價(jià)格便宜，因此能夠很好地滿足上述場合對(duì)大量數(shù)據(jù)緩存的需求。但DDR SDRAM的接口不能直接與現(xiàn)今的微處理器和DSP的存儲(chǔ)器接口相連，需要在其間插入控制器實(shí)現(xiàn)微處理器或DSP對(duì)存儲(chǔ)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.
