Description: An 8-QAM communications channel simulation in Simulink, constructed from a 16-QAM model and using an I,Q correlation receiver.
QAM (quadrature amplitude modulation) is a method of combining two amplitude-modulated (AM) signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation (PAM) in digital systems, especially in wireless applications. In a QAM signal, there are two carriers, each having the same frequency but differing in phase by 90 degrees (one quarter of a cycle, from which the term quadrature arises). One signal is called the ‘I’ signal, and the other is called the ‘Q’ signal. Mathematically, one of the signals can be represented by a sine wave, and the other by a cosine wave. The two modulated carriers are combined at the source for transmission. At the destination, the carriers are separated, the data is extracted from each, and then the data is combined into the original modulating information. -An 8-QAM communications channel simulation in Simulink, constructed from a 16-QAM model and using an I,Q correlation receiver.

Description: This document describes a MATLAB implementation of the 3GPP Spatial Channel Model (SCM) [3GPP03]. The accompanying MATLAB code implements the system level channel model described in Section 5 of [3GPP03], except the “far scatterer clusters” feature from Section 5.5.2 and the intercell interference feature from Section 5.7. These features were left out of the implementation because they make certain restricting assumptions about the network layout. The current implementation has no built-in assumptions on network geometry and is hence usable for a variety of simulation purposes.
