ROC

这是一个将时间改换到深度的程序,这是一个matlab程序(this is a program for time to depth)

本程序是QPSK信号在瑞利衰落信道下的仿真，已经过本人验证，适合初学者(This procedure is QPSK signal simulation in Rayleigh fading channel, I have been verified, suitable for beginners)

PSO算法的matlab实现，在6.5版本测试过，其他版本不保证能够马上用(PSO algorithm matlab realized, tested in the 6.5 version, does not guarantee that other versions can immediately use)

说明：  二分法检索（binary search）又称折半检索，二分法检索的基本思想是设字典中的元素从小到大有序地存放在数组（array）中， 　　首先将给定值key与字典中间位置上元素的关键码(key)比较，如果相等，则检索成功；(Dichotomy search (binary search), also known as binary search, the basic idea of ??dichotomy is set to retrieve the dictionary from small to large elements stored in an orderly array (array), the first key the given value on the middle element of the dictionary The key code (key) comparison, if they are equal, then the retrieval success )

一个简单正弦信号经过匹配滤波后计算SNR，并绘制时频域图片(Calculated a simple sinusoidal signal after matched filtering SNR, and draw the frequency domain picture)

说明：  实现OFDM多种信道条件下的LS时域频域信道估计方法仿真(Simulation of LS time domain and frequency domain channel estimation method for OFDM with multiple channels)
