[matlab例程] QAM
说明:Quadrature amplitude modulation is a method of combining two amplitude-modulated signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation in digital systems, especially in wireless applicati<karthi> 在 2025-11-09 上传 | 大小:1kb | 下载:0
[matlab例程] QPSK
说明:Quadrature Phase Shift Keying is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts in 0, 90, 180, or 270 degrees-Quadrature Phase Shift Keying is a form of Phase Shift Keying in<karthi> 在 2025-11-09 上传 | 大小:1kb | 下载:0
[matlab例程] BPSK
说明:In BPSK modulation, the phase of the RF carrier is shifted 180 degrees in accordance with a digital bit stream. A form of phase modulation in which the modulating function shifts the instantaneous phase of the modulated wave between predetermined dis<karthi> 在 2025-11-09 上传 | 大小:1kb | 下载:0
[matlab例程] adaptive_heterodyne
说明:自适应外差滤波器matlab代码:采用调制技术,控制正余弦信号对准干扰的频率,将输入的干扰搬移到的低频进行滤波,滤波处理后的信号再经过一次调制搬移到原来的频率位置,这样我们就得到了合适的干扰复制信号,再将输入信号和干扰复制信号进行差分运算达到抑制干扰的目的-Adaptive heterodyne filter matlab code<shasha> 在 2025-11-09 上传 | 大小:1kb | 下载:0
