matlab codes for basic algorithms for MRI

一种简易的电机模型 很好用啊 希望对大家有帮助啊(A simple motor model with very good ah we hope to help)

script that converts file to binary stream and convolutes it

MATLAB自带的函数XCORR好象有点像卷积,如果要是求一个PN序列的自相关,我看一般的资料都是用我这个办法求PN序列相关的。(MATLAB comes with seems a bit like a function XCORR convolution, if the request if the autocorrelation of a PN sequence, I see the general information are seeking ways to use my PN sequence related.)

只要输入信号的中心频率和带宽，自动生成带通滤波器采样率、信号保护带、采样率误差容限(Just enter the center frequency and bandwidth of the signal, automatically generated bandpass filter sample rate, signal protection zone, the sampling error margin rate)

reduction to papr in ofdm with Peak Windowing: The basic idea of peak windowing is to multiply the envelope of OFDM signal with a weighting function . Therefore, ~xE (t)= xE (t) f (t) where XE(t) =[x(t)] The weighting function given by: f (t)= 1-Σ α .w(t- t ) t-t w(t) : is the window function. t : denotes the position of a local maximum of the envelop xE(t) . α : attenuation constant . When the amplitude of envelop amplitude of the OFDM signal exceeds a threshold, a window function is applied to the envelop of the OFDM signal to eliminate the peak amplitude. windowing results in a smooth signal. Hanning window function will be used for w(t) As a matter of fact , other windows such as cosine, hamming and Kaiser may be employed.

Create a channel object that describes the channel that you want to use. A channel object is a type of MATLAB variable that contains information about the channel, such as the maximum Doppler shift.
