图3 DVB-S2接收机比特级处理 为了实现DVB-S2端到端的仿真,我们需要用到MATLAB的help文档和function。 首先,我们需要下载DVB-S2 LDPC Parity Matrices文件,用于LDPC编解码。 然后,我们需要对DVB-S2进行配置。 指定cfgDVBS2结构体来定义DVB-S2传输配置参数。ScalingMethod属性适用于MODCOD在[18,28]范围内(即仅为APSK...
与之相关的还有DVB-S2X和DVB-RCS2等,以及最近几年提出的5G-NTN。 本文基于MATLAB的DVB-S2端到端示例,简述如何搭建仿真链路,同时重点关注如何让进行接收机同步处理。 这个示例演示了如何测量具有恒定编码和调制的单流数字视频广播卫星第二代(DVB-S2)链路的误码率(BER)和误包率(PER)。该示例详细描述了符号定时和...
The satellite communication channel mostly suffers from signal fading mainly resulted from atmospheric rain attenuation and ionospheric scintillation.Rain attenuation affects these signals severely by absorbing properties of the water,while amplitude and phase of the received signal will be distorted frequently...
Alternatively, to run the model, execute this command at the MATLAB command window. sim dvbs2hdlReceiver The MODCOD value must be a row vector. Each element of the row vector corresponds to a frame. Note: Use QPSK modulated frames initially to achieve time frequency and phase synchronization....
同步处理过程的实现依赖于MATLAB的示例代码和功能。首先，需要下载用于LDPC编解码的DVB-S2 LDPC Parity Matrices文件。然后，配置DVB-S2传输参数，包括ScalingMethod属性和UPL属性。系统仿真参数包括信道带宽（例如36MHz），以及符号速率计算。创建DVB-S2波形时，使用HelperDVBS2RxInputGenerate辅助函数。接收端的...
If the MAT-file is not available on the MATLAB® path, then the example downloads them from mathworks.com. Internet connectivity is required to perform this download operation. The model is shown in the following figure: The ground station transmitter and uplink path are shown in ...
I'm using MATLAB's example code from this link: End-to-End DVB-S2X Simulation with RF Impairments and Corrections for Regular Frames. My question is: Does the provided example code support signal processing with a 200Msps sampling rate and 20 samples per symbol config...
