A photonic analog to digital converter (pADC) includes an electronic I/Q generator, an optical sampler, and an optical detector. The electronic I/Q generator is configured to receive an RF signal and to generate an electronic in-phase signal I and an electronic quadrature-phase signal Q based on the received RF signal. The optical sampler includes one or more optical intensity modulators configured to receive the electronic I and Q signals from the electronic I/Q generator, and to modulate optical pulses to provide modulated optical I and Q signals based on the received electronic I and Q signals from the electronic I/Q generator. The optical detector includes a plurality of photodetectors, and is arranged to receive the modulated optical I and Q signals from the optical sampler and to convert the modulated optical I and Q signals into modulated electronic I and Q signals.

Photonic direct sampling digital receiver

A wireless transmission security apparatus includes a wireless device (WD) adaptor, wherein the WD adaptor is configured to contain a portion of radio frequency (RF) radiation emanating from an antenna of an associated wireless communication device, wherein the WD adaptor is selectively communicatively couplable to the wireless communication device at a selected antenna coupling point of the wireless communication device, and a base transceiver station (BTS) adaptor, wherein the WD adaptor and the BTS adaptor are communicatively coupled via uplink and downlink signals, wherein the frequency of the uplink signal is different from a frequency of a native RF uplink signal emanating from the wireless communication device and the downlink signal is different from a frequency of a native RF downlink signal emanating from the BTS.

System and method for wireless transmission security

The present invention is an apparatus and method for simultaneously processing multiple communication and navigation signals. An apparatus of the present invention may comprise a single receiver with a direct radio frequency (RF) sampling front end, a single analog to digital converter, a digital downconverter and a digital signal processor. In an embodiment of the invention, the receiver of the present invention may simultaneously process navigation signals in the 108-118 MHz band and communication signals in the 118-137 MHz band.
