电力系统潮流计算算法，用matlab编写(tidal current)

一种具有提示功能的文本框，可以根据实际使用进行重新，具有很好的参考价值(A text box with prompts that can be re-based on actual use, a good reference value)

speech signals in gsm

说明：  经典信号小波分解matlab算法,注解很清楚，可以直接执行(classic wavelet for analysing signal)

语音处理矢量量化技术，用于从一帧语音中提取特征矢量 相当有用(in speech signal process vector quantization technology with matlab code)

OFDM implementation using 64QAM

用于时频分析算法，数值分析的EULER法，LCMV优化设计阵列处理信号，用于建立主成分分析模型，主同步信号PSS在时域上的相关仿真，基于chebyshev的水声信号分析。 ( For time-frequency analysis algorithm, EULER numerical analysis method, LCMV optimization design array signal processing, Principal component analysis model for establishing, PSS primary synchronization signal in the time domain simulation related, Based chebyshev underwater acoustic signal analysis. )

说明：  用于广播系统发射机的数字中频调制采用64QAM的方式，使用matlab中的altera dsp builder实现。(64QAM modulator, used in broadcast system digital IF modulation.)

The PID controller is the most widely used controller in industrial systems. However, appropriately tuning a PID controller is not an easy task although it has only three parameters at most. This submission provides a tool for beginners to learn PID tuning.

本文件是有关于QPSK仿真的matlab源码。(This document is QPSK simulation on matlab source.)
