用MATLAB实现绘制带通滤波器的损耗函数曲线(Using MATLAB drawing of the loss of band-pass filter function curve)

QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

只需修改路径就可以直接处理心电数据，但是数据格式是txt的，而且数据是R的横坐标。可以画散点图，密度图，功率谱分析等。(It is useful and easy for processing the ECg data with MATLAB。)
