摘要

1992年,Wornell和Oppenheim对利用小波理论形成的调制进行了研究。在其他一些研究中,证明了该调制可以在少数信道上存活,并且在某些应用中具有可靠性。由于这种调制采用了分形的概念,故称为分形调制。分形调制是将信息信号插入自分形相似的分形信号中形成的。这种调制技术有可能取代OFDM(正交频分复用),后者目前在一些最新的电信技术中使用。本研究的目的是在不使用AWGN和瑞利信道的情况下,使用数字信号处理入门工具包(DSK) TMS320C6713实现分形通信系统,以获得理想的系统性能。从仿真结果使用MATLAB7.4。表明该通信系统在某些信道上具有比其他通信系统更好的性能。而在TMS320C6713 Code Composer Studio (CCS)上使用(DSK)实现时,可以得出分形通信系统在某些测试中具有更好的执行时间。

Fractal Communication System Using Digital Signal Processing Starter Kit (DSK) TMS320c6713
In 1992, Wornell and Oppenheim did research on a modulation which is formed by using wavelet theory. In some other studies, proved that this modulation can survive on a few channels and has reliability in some applications. Because of this modulation using the concept of fractal, then it is called as fractal modulation. Fractal modulation is formed by inserting information signal into fractal signals that are selffractal similary. This modulation technique has the potential to replace the OFDM (Orthogonal Frequency Division Multiplexing), which is currently used on some of the latest telecommunication technologies. The purpose of this research is to implement the fractal communication system using Digital Signal Processing Starter Kit (DSK) TMS320C6713 without using AWGN and Rayleigh channel in order to obtain the ideal performance of the system. From the simulation results using MATLAB7.4. it appears that this communication system has good performance on some channels than any other communication systems. While in terms of implementation by using (DSK) via TMS320C6713 Code Composer Studio (CCS), it can be concluded that the fractal communication system has a better execution time on some tests.
