    摘要： A multi-dimensional beamforming device that performs consecutive one-dimensional operations. For example, beamsteering for a two-dimensional array can be include a projection of a beam onto each of the respective axes of the array. In such a device, a first beamforming processing element is used to form multiple beams for each array output along a given row. In a preferred embodiment, sequential output vectors from the first processing element are then applied to a transposing or corner turning memory and the data are reformatted such that all elements on a given column of the array are applied to a second beam forming processing element.

    摘要： A wireless communication system employs directive antenna arrays and knowledge of position of users to form narrow antenna beams to and from desired users and away from undesired users to reduce co-channel interference. By reducing co-channel interference coming from different directions, spatial filtering with antenna arrays improves the call capacity of the system. A space division multiple access (SDMA) system allocates a narrow antenna beam pattern to each user in the system so that each user has its own communication channel free from co-channel interference. The position of the users is determined using geo-location techniques. Geo-location can be derived via triangulation between cellular base stations or via a global positioning system (GPS) receiver. The system can be optimized by applying partially adaptive processing algorithms, which are seeded by geo-location data.

    摘要： The need for multiple, cost-effective deployment of an underwater camera has resulted in the development of a low-power high-resolution imaging system using a sparse array. The system can be used for undersea acoustic mine-field reconnaissance and mine-hunting systems for example, this imaging sonar is portable enough for use in a diver's hands or in a remote imaging sonar on an unmanned undersea vehicle in shallow waters. The present system can simultaneously focus many signals using multiple CCD/CMOS, programmable time-delay beamforming circuits connected to a sparsely-populated 2D acoustic array, is being developed. Using this approach, a real-time image can be formed to search for mine-like objects. To make a sparse array, the combination of low insertion loss and wide bandwidth performance is important for realizing acceptable imaging performance with low illumination levels.
