This research focuses on the development of robust interference mitigation and variable rate/rate-adaptive antijam signaling techniques. In the development of robust interference mitigation, both nonlinear and linear adaptive filtering techniques are used for mitigating a variety of interference sources, including wideband/impulsive interference, multipath, and multiple-access interference (as well as intelligent jammers such as spoofers or repeat-back jammers). Such techniques represent an efficacious way to combat a wide range of potential communications signaling threats. In the development of variable rate signaling techniques, rate-adaptive modulation represents a relatively new line of research focusing on the development of a robust multiuser signaling paradigm capable of supporting heterogeneous, variable-rate data traffic. The signaling system that we are developing proposes dynamically adjusted trade-offs between system processing gain and coding gain, quality of service, and data rate for multiple users in potentially hostile signaling environments.
