Abstract
The limited amount frequency spectrum available to wireless comnmnication systemsmakes it difficult to satisfy the rapidly growing demand for wireless service. Spectral efficiency can be increased by using higher order modulation schemes. However this come at the cost of increased probability of error. In this paper we investigate through MATLAB simulation, the implementation of orders of Quadrature Amplitude Modulation (QAM) more commonly used in wired networks. The BER performance of 64, 128, 256, 512, 1024, 2048, 4096, and 8192 QAM signals in the presence of Rayleigh and Rician multipath channels with additive white Gaussian noise are simulated.
