The information is divided into Inphase and Quadrature components. The outputs of both modulators are algebraically summed and the result is then transmitted. Due to the orthogonal characteristics of the two channels, the Inter Symbol Interference, ISI. ofdm using 64 qam matlab code Search and download ofdm using 64 qam matlab code open source project / source codes from.

In a.

Amplitude Modulation Matlab Code Amplitude modulation AM is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength amplitude of the carrier in proportion to the waveform being sent. I am trying to do modulation and demodulation for 16-QAM and then trying to compare theoretical and simulated BER. I am not getting simulation-line in the graph. I can not understand what is wron.
