Performance Analysis of Modified M-ARY PSK and QAM Signaling Schemes in the Presence of Noise and Jamming.

Abstract

The purpose of this thesis is to evaluate and compare the performance of certain M-ary digital modulation schemes such as MPSK, QAM and certain modifications to these which have not been considered in previous analyses. The performance of these receivers is evaluated in terms of probability of error as a function of signal to noise ratio (SNR). Design trade-offs are considered and their effect on system performance evaluated in terms of its vulnerability to jamming. Using a colored Gaussian noise model, jamming effects are evaluated by determining the receiver error probability as a function of both SNR and jamming to signal ratio (JSR). An optimum jamming scheme that is derived using a maximum power constraint is presented and its effect on the performance of a 16-QAM receiver designed to operate in an additive white Gaussian noise (AWGN) only interference is evaluated.
