Abstract: Matrix operations circuitry for performing operations on submatrices of an input matrix includes a first working memory in which individual ones of the submatrices are operated on. The first working memory has a first submatrix size. The matrix operations circuitry also includes a second working memory in which a collection of the submatrices, that have been operated on in the first working memory, is operated on. The second working memory has an optimum burst size, and the first submatrix size is matched to the optimum burst size.

Abstract: A system and method for managing control information in a wireless communications system. The method comprises broadcasting a predetermined number of preambles through beamforming from a base station, detecting, by a subscriber station, a predetermined frame associated with one selected preamble that has the highest power level, and identifying one or more subcarriers for carrying control information through the selected preamble.

Abstract: Techniques are provided herein for generating multiple radiation patterns. An antenna system comprises an antenna array having one or more antennas for providing a first radiation pattern and a second radiation pattern, a transform matrix for transforming one or more inputs into one or more outputs according to a transform function, wherein the outputs of the transform matrix provide signals to the antennas with predetermined phases and magnitudes for generating the first and second radiation patterns, and a transmitter for providing a first set of signals corresponding to the first radiation pattern and a second set of signals corresponding to the second radiation pattern to inputs of the transform matrix.

Abstract: An integrated database indexing system includes a database containing data and a query source communicably connected to the database. A query router connected to the query source communicates with an index engine. The index engine accesses an index associated with the data in said database. When query source communicates a command to the query router, the query router communicates the command to the index engine such that the index engine identifies result data in the data contained by the database.
