Abstract: A system and method of enabling digital beamforming (DBF) for use with RF receiver systems with a multi-element array antenna having short repetitive synchronizaton sequences in a noise and/or jamming environment.

Abstract: The method and system provides an improvement in signal to noise plus interference without utilizing a calculated covariance matrix or calibrated antenna array, and does not require knowledge of the array geometry. The system utilizes the cross correlation of the output of each antenna element to estimate a weight vector for resolving a signal in a multiple simultaneous source environment.

Abstract: A method of determining the size of a sub-array for an antenna array is described. The method includes choosing a number of elements of a sub-array of antenna elements. Further, the method includes determining a direction of arrival of the signal using data from the sub-array. The method also includes computing weights for the antenna array. Further still, the method includes determining whether the size of the sub-array meets a predetermined criteria.

Abstract: A bandwidth management system for a remote repeater network for modifying a first signal to create a second signal within the bandwidth of a communications link, transferring the second signal across the communications link, and reconstructing the first signal at the remote end of the communications link. The bandwidth management system featuring several mixing modes for performing the signal conversion and reconstruction. The system offering a calibration feature to correct for phase distortions introduced in reconstruction of the original signal. The calibration feature incorporating signals from a global positioning satellite system for reconstruction.
