音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)

频谱分析，用于对等时间间距的序列进行频谱分析(spectrum analysis, for the time interval, such as the sequence spectrum analysis)

关于滤波的设计 及示例,pdf格式，在matlab下设计完成！(the design for the filter!)

OFDM信号具有高峰均功率比的特点，研究交织技术在抑制OFDM信号峰值平均功率比（PAPR）中的应用。论文首先阐述了OFDM的基本原理和关键技术，简单介绍了目前降低PAPR的几种方法，在对交织法降低OFDM系统的PAPR进行理论分析的基础上，提出了一套合理的交织方案――利用分组交织器和伪随机交织器降低PAPR，最后通过MATLAB仿真得出结论。(OFDM signal has a peak to average power ratio characteristic of interwoven OFDM technology in the inhibitory signal peak-average power ratio (PAPR) of the application. Thesis first expounded the basic principles of OFDM and key technologies, the simple introduction of the current of several methods to reduce PAPR, intertwined in the law to reduce PAPR of OFDM system, the theoretical analysis, based on a set of reasonable intertwined programs- use Packet interleaver and the pseudo-random interleaver to reduce PAPR, the final conclusion through MATLAB simulation.)
