matlab code for estimation in channel

本课题研制了一种宽频带的数字锁相放大器，可以完成自动增益和相位 可调整，最长积分时间为100s，适合于频率从10Hz到10kHz，幅值从100nV 到10mV的微弱正弦信号检测。测量结果表明，当采样点数N大于8192时， (This project developed a wideband digital lock-in amplifier, can be completed automatically adjustable gain and phase, the longest integration time of 100s, suitable for the frequency range from 10Hz to 10kHz, amplitude from 100nV to 10mV of weak sine signal detection. The measurement results show that, when the sampling point number N is greater than 8192 hours,)

利用FFT快速计算，线性排列阵子方向图。( This function computes and returns the gain radiation pattern for a linear array It uses the FFT to computes the pattern *INPUTS********** Nr ==> number of elements dolr ==> element spacing (d) in lambda units divided by lambda theta0 = steering angle in degrees winid ==> use winid negative for no window, winid positive to enter your window of size(Nr) win is input window, NOTE that win must be an Nr X 1 row vector nbits ==> number of bits used in the pahse shifters negative nbits mean no quantization is used *OUTPUTS****************** theta ==> real-space angle patternr ==> array radiation pattern in dBs patterng ==> array directive gain pattern in dBs ***************************************** )

说明：  利用Matlab及Simulink建立仿真系统，对PCM量化信噪比进行仿真测试，要求对输入的正弦波进行采样、量化和PCM编码，计算并画出量化信噪比曲线，比较量化信噪比理论值与实际值。(Using MATLAB and Simulink to set up simulation system to simulate and test the quantized signal-to-noise ratio of PCM, it is required to sample, quantize and PCM code the input sine wave, calculate and draw the quantized signal-to-noise ratio curve, and compare the theoretical value and the actual value of the quantized signal-to-noise ratio.)
