Shi, Huifang Sun, 1999 NOTE: (1) Test Pattern: Input image: MTF (modulation transfer function) (given Matlab code) and image with the size 352*288 and 320*240 Output Reference signal: MTF (modulation transfer function) (given Matlab code) and image with the size 352*240 PSNR= 10 * ...
Previously, I was able to process signals with a sampling rate of 20Msps and 2 samples per symbol without any issues. I'm using MATLAB's example code from this link:End-to-End DVB-S2X Simulation with RF Impairments and Corrections for Regular Frames. ...

3.9.3.3 Frequency demodulation Frequency demodulation consists of recovering the signal that carries the information or modulating signal that is carried by the variations of the carrier frequency. To this end, we make use of the synoptic diagram, based on a PLL, in Figure 3.82. Sign in to dow...
Fig. 8.Block diagrams of the modulation and demodulation processes of OFDM that take place at the transmitter and receiver ends, respectively. OFDM has been extensively used in broadband wired andwireless communicationsas it is robust against ISI and scales well with increasing data rates (Armstrong...
针对这一误差,介绍了开环系统中频差校正原理,然后通过滑动窗口求均值的方法实现平均相位误差校正,并利用Matlab仿真证实,在同样信噪比下,采用平均相差法得到的误码率比直接相差提取的方法低很多。 3. A scheme for jointfrequency offsetand spread spectrum code time delay acquisition was proposed,and the noise and...
The network model inputs the super-low frequency modulation signal sequence with the size of 20 * 20 and outputs the demodulation signal with the size of 4 * 1. Firstly, 3200 super-low frequency BFSK modulated signals and corresponding original binary signals were obtained through MATLAB ...
