MATLAB provides a powerful platform for implementing and simulating digitalmunication systems. The code snippet provided in the previous section demonstrates how QPSK modulation and demodulation can be implemented using MATLAB. The code generates a random QPSK modulated signal, displays the signal in a ...
简介:该通信系统主要用于高质量图像传输,如无人机、视频监控等场景。系统采用QPSK调制解调、扩频技术和LDPC译码,确保复杂电磁环境下的稳定性和清晰度。MATLAB仿真(2022a)验证了算法效果,核心程序包括信道编码、调制、扩频及解调等步骤,通过AWGN信道测试不同SNR下的性能表现。
1.算法仿真效果 matlab2022a仿真结果如下: 2.算法涉及理论知识概要 在现代通信系统中,扩频技术被广泛应用于数字通信链路中。扩频技术通过将要传输的信息序列与一个宽带的伪随机码序列进行卷积,将原始信号转换成…
