在理論分析循環(huán)碼編碼和譯碼基本原理的基礎上，提出了基于單片機系統(tǒng)的(24，16)循環(huán)碼軟件實現(xiàn)編碼、譯碼的方案。仿真結果表明(24，16)循環(huán)碼能有效地克服來自通訊信道的干擾，保證數(shù)據(jù)通信的可靠及系統(tǒng)的穩(wěn)定，使誤碼率大幅度降低。本論文對(24，16)循環(huán)碼的研究結果表明，可以有效地降低錯誤概率和提高系統(tǒng)的吞吐量，實現(xiàn)糾錯僅需要在接收端增加有限的存儲空間和計算復雜度，具有一定的實用價值。 Abstract: Based on analyzing the theory of encoding and decoding of cyclic code， this paper showed the schemes of encoding and decoding of(24，16)cyclic code by the software and based on microcontroller. Simulation results show that using (24，16) cyclic codes can effectively overcome the interference from communication channel， ensure the reliability and stability of data communication systems， and reduce the bit error rate greatly. The results of this paper show that by using the (24，16) cyclic code， the error rate can be reduced and the system throughput can be improved. Meanwhile， the system only needs to enlarge limited storage space and computation the complexity at the receiving end to realize error correction. Thus the (24，16) cyclic code has a practical value.

為深入了解基于UC3854A控制的PFC變換器中的動力學特性，研究系統(tǒng)參數(shù)變化對變換器中分岔現(xiàn)象的影響，在建立Boost PFC變換器雙閉環(huán)數(shù)學模型的基礎上，用Matlab軟件對變換器中慢時標分岔及混沌等不穩(wěn)定現(xiàn)象進行了仿真。在對PFC變換器中慢時標分岔現(xiàn)象仿真的基礎上，分析了系統(tǒng)參數(shù)變化對分岔點的影響，并進行了仿真驗證。仿真結果清晰地顯示了輸入整流電壓的幅值變化對系統(tǒng)分岔點的影響。 Abstract: In order to better understand the dynamics characteristic of power factor correction converter based on UC3854A， and make the way that parameters change influences the bifurcation phenomena of the system clearly. The math model of the two closed loop circuits to the Boost PFC （Power Factor Correction） converter controller was built. Then， with the help of Matlab， the simulation for nonlinear phenomena such as chaos and slow-scale bifurcation in the PFC converter was made. Finally the factors that have influence to the phenomenon of bifurcation under slow-scale in PFC converter were analyzed. The simulation results clearly show the parameters change influences the bifurcation point of the system.
