In the context of array sensors such as radar, sonar, and communications receiver arrays, the present invention exploits the geometry phase components of radiated wavefronts associated with the signals of interest in order to reduce the bandwidth requirements for DOA and beamforming processing. Additionally, geometry phase is exploited in order to effectively increase the resolution of an array without changing the size of its physical footprint or the number of array elements. Other embodiments of the invention include the use of virtual array elements for increase in effective array size.

Phase arrays exploiting geometry phase and methods of creating such arrays

A communications network which is capable of effectively and efficiently handling fading between mobile wireless user terminals of a packet-switched network with minimal overhead and packet loss, and a method for using the same. The communications network employs an origination mobile terminal and surrounding macroscopic mobile terminals and/or surrounding fixed infrastructure. Communication is established between the origination mobile terminal and surrounding macroscopic mobile terminals and/or surrounding fixed infrastructure. The communication is established via modified request to send (RTS) and clear to send (CTS) messages, wherein the modified messages provide for an additional two sets of k unicast addresses where k equals the maximum number of routes available per route entry in the origination mobile terminal's route table.

System and method for performing macro-diversity selection and distribution of routes for routing data packets in Ad-Hoc networks

A system and method for efficiently and effectively simulating hardware-in-the-loop testing of a wireless communications network. The system and method employs an optical matrix-vector multiplier (MVM) for performing optical signal processing to simulate radio frequency (RF) signal propagation characteristics in a mobile wireless communications network. Specifically, the system and method employs an optical modulator, which is adapted to modulate optical energy with signal energy, such as radio frequency (RF) signal energy, propagating from a first group of transceivers of the network to form a vector of optical signals. The optical matrix-vector multiplier (MVM) receives the vector of optical signals, and has a matrix of optical channel weights which are modifiable in accordance with desired parameters to represent at least on parameter of the wireless network. The optical MVM is further adapted to output signals based on the received vector of optical signals and the optical channel weights. The system and method further employs a detector device, adapted to detect the output signals and to provide the output signals as an output vector of signals to a second group of transceivers of the network.
