Abstract

The hybrid system is an extension of the state-space system model which allows for random and abrupt changes in the model parameters. It has been used in the control and estimation literature to model a number of phenomena including subsystem failures, piecewise approximations for nonlinear systems, and target maneuverability. This paper describes a novel application of the hybrid system to the field of digital communications. Specifically, the hybrid system is used to model pulsed narrowband interference in a direct-sequence spread-spectrum (DS/SS) communication system. The resulting optimum receiver is easily derived but too computationally complex to be practical. A suboptimal but more practical receiver is presented along with a method for approximating the receiver's performance. The approximate performance is then compared to the performance obtained through computer simulations.
