摘要： Methods, systems, and devices for reducing the impact of a jamming signal on wireless communications are described. Generally, the described techniques provide for receiving a first signal at a first antenna and receiving a second signal at a second antenna. An anti-jammer manager may process the first signal and the second signal to obtain a residual signal. The processing may include determining a weighting factor based at least in part on a correlation between the first signal and the second signal, applying the weighting factor to the first signal to create a weighted first signal, and subtracting the weighted first signal from the second signal to obtain the residual signal. A demodulator may demodulate the residual signal to obtain symbol information. A decoder may decode the symbol information to obtain data. The techniques may be used to recover a desired signal portion from a jammed signal.

摘要： Disclosed is a Link 16 terminal having a receiver and a transmitter. The receiver may be configured to process received signals in a receive mode to produce digitized samples, which may then be processed in a digital signal processor. The transmitter may be configured to produce a transmit signal that is provided to an antennas for transmission during transmit mode. The transmit signal may also be provided to the receiver in transmit mode to produce digitized samples of the transmit mode, may then be processed in a digital signal processor for compliance with requirements for Link 16 transmissions.

摘要： A transceiver having substantially improved capacity and interference mitigation. The transceiver comprises a first direct conversion receiver (DCR) and a plurality of additional DCRs, each of the plurality of additional DCRs having essentially identical constituent components to the first DCR. Each DCR does a direct down-conversion from RF to a complex pair of baseband I and Q components. The complex signal pair from each DCR is digitized and further processed in a modem module where the signal is optimally filtered, demodulated, and error-corrected. The modem module reconstructs the message information contained in each signal from all of the DCR's, simultaneously providing the demodulated data that was contained in the RF signals. The dynamic range of the system is extremely large (i.e., approximately 80 dB).
