Set the modulation order, and create a data sequence that includes a complete set of symbols for the modulation scheme.

This experiment primarily concerns the design and implementation of a Quadrature Amplitude Modulation (QAM) transmitter. QAM is a widely used method of transmitting digital data over …

May 3, 2020 · In this post I am hoping to provide an explanation of Quadrature Amplitude Modulation and work through an implementation using MATLAB. I'll attempt to make …

Jun 7, 2016 · The standard way to use quadrature modulation is to generate a complex baseband signal (i.e., two real-valued baseband signals), which is easy if your data are digital (just use a …

Instead of using only in-phase component with real (y), you can use abs (y) which gives the magnitude of in-phase and quadrature components. But, I would assign 16 distinct frequencies …

Polar View shows amplitude and phase of it(t), qt(t) and yt(t) combined signal for transmission at a given frequency f. Magnitude of i(t) and q(t) vary with time, representing information in the …

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 …

This project simulates a complete 16-QAM (Quadrature Amplitude Modulation) digital communication system using MATLAB. It includes the transmitter, channel model, and …

The Rectangular QAM Modulator Baseband block modulates the input signal using M-ary quadrature amplitude modulation with a constellation on a rectangular lattice. The output is a …

This MATLAB function returns the complex envelope of the QAM for message signal X.
