[matlab8QAM

Description: 利用matlab仿真软件,实现8QAM调制。在实现时采用正交调幅的方式,某星座点在I坐标上的投影去调制同相载波的幅度,在Q坐标上的投影去调制正交载波的幅度,然后将2个调幅信号相加就是所需的调相信号。-Use of matlab simulation software to achieve 8QAM modulation. In achieving the adoption of quadrature amplitude modulation means of a constellation in the I coordinates of the projection to the modulation of the amplitude-phase carrier, in the Q coordinates of the projection to the range of carrier orthogonal modulation, and then the sum of two AM signals is the required phase modulation signal.

[Communication-MobileDesign of Digital Simulation system for QAM

Description: The digital simulation system using MATLAB to illustrate the Quadrature Amplitude Modulation (QAM). QAM is a modulation scheme to convey two digital bit streams which can be converted to symbol signals by modulating the amplitudes and the phase of two carrier waves. First, we transmit a signal composed of two different 1024 bit streams and modulate them using QAM. Next, at the receiver, we demodulate them using an orthogornality of two carriers and matched filters. We also conduct the error analysis of two sampled signals in order to observe how the probability of making bit errors changes depending on the inverse of Power Spectral Density (PSD) of Additive White Gaussian Noise (AWGN).
