Modulation-QPSK-and-OQPSK-in-MatLABtn**dy 上传4.65 KB 文件格式 zip 这段代码实现了QPSK(四相移键控)及其改进的OQPSK(偏移QPSK)调制。QPSK通过将每个符号映射到特定的相位来传输两个比特,但可能存在相位跳变导致信号失真的问题。OQPSK通过在相位变化前将信号延迟半个符号周期来解决这个问题,从而减少了跳变,提高...
在通信领域,调制解调技术一直是一个核心的研究方向。本文将探讨使用MATLAB进行OFDM(正交频分复用)和OTFS(正交时间频谱)技术,在16QAM(16正交幅度调制)和QPSK(四相移位键控)调制下,结合LDPC(低密度奇偶校验码)和Turbo码在高斯白噪声和频率选择性衰落信道下的误比特率性能仿真。
division multiplexing (OFDM). It then passes the signal through an additive white Gaussian noise channel before demultiplexing and demodulating the signal. Finally, the system calculates the number of bit errors. To model the system, this example showcases the use of the MATLAB® System object...
