Abstract

A general FSK spectrum simulator is written in MATLAB(R) to evaluate the optimum filtering for FSK modulation systems in near-far interference limited channels. In addition, only constant envelope (CE) signals are considered because of their demonstrated energy efficiency. The Fourier Uncertainty Relation is used to evaluate the relative performance of partial response filtering to M-ary signaling. Simulation results are compared with hardware measurement. A similar program is in process for CE-PSK modulation.
