Description: BER of QAM at Different bitrates, The
resulting bit error rate the Monte Carlo
simulation for the different QAM bit rates (4 to 1024) have been exported to the Matlab
workspace as a vector of error values for each bit rate versus the noise power spectral density (Eb/No) variations. The figure illustrates the fact that at higher transmission bit rates, the error in the received signal increases. Therefore, it becomes a tradeoff between the transmission speed and the accuracy of the transmitted data. The increase in the error or distortion in the received signal may add to the complexity of the receiver design in order to recover the original signal or information.-BER of QAM at Different bitrates, The

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). Platform: |
