AbstractUHF MILSATCOM channel availability is limited by sporadic narrowband interference. When frequency separation between the interferer and signal-of-interest is insufficient, use of conventional fixed-frequency filtering will result in unacceptable distortion to the signal-of-interest. In this Phase I project, GIRD Systems proposes novel algorithms and approaches for detection and excision of interference from an in-channel desired signal. The proposed algorithms will be analyzed and evaluated with respect to customer-identified typical channel conditions. The algorithms demonstrating the greatest interference mitigation potential will be identified and extended to the multi-interferer, multi-channel case. Finally, preliminary hardware design will be performed. In Phase II, GIRD Systems will develop and deliver to the Navy prototype interference excision hardware.
