    • A matrix-fed circular array system includes a plurality of antennas, a plurality of azimuth matrices in communication with the antennas, and a plurality of elevation matrices in communication with the azimuth matrices. The array system forms M×N beams, where M is the number of azimuth beams, and N is the number of elevation beams. In another embodiment, through the use of a Shelton-Butler or Butler matrix which includes a plurality of hybrids, the system outputs omni-directional pancake-shaped radiation patterns that are isolated from each other when a communication signal is input into the system. In yet another embodiment, the system uses a beam forming network including two Shelton-Butler matrices. A first one of the Shelton-Butler matrices creates omni-directional pancake beams that are isolated from each other, and a second Shelton-Butler matrix creates multiple directive beams in an azimuth plane.

    • A technique automatically handles a failure during online data migration from a source array to a target array. While a host initially accesses data from the source array using multipath I/O software, the technique involves (i) transitioning the source array to a passive mode, and the target array to an active mode, and (ii) beginning a data transfer operation which transfers data from the source array to the target array. The technique further involves modifying the data on both the target array and the source array in response to modification commands sent to the target array from the host while the data transfer operation is ongoing. The technique further involves automatically failing back to providing access to the data from the source array in response to an event in which the target array loses communication with the source array for a predefined amount of time.

    • A method for operating a CDMA communications device includes receiving at an antenna array M different summations from a mixture of source signals provided by M signal sources, and providing the M different summations to a receiver assembly. The receiver assembly includes a first signal path and a second signal path parallel to the first signal path. In the first signal path, a mixing matrix including the M different summations of the M source signals is formed, and at least one source signal is separated from the mixing matrix. A determination is made if the separated source signal is an interferer source signal. In the second signal path, the M different summations are delayed corresponding to a delay introduced in the first signal path. The first signal path provides to a summer the separated source signal if the separated source signal is an interferer source signal, and the second signal path provides to the summer the M different summations after being delayed. The summer removes the interferer source signal if present from the M different summations after being delayed.

    • A communications device includes an antenna array for receiving different summations of source signals from a plurality of signal sources, a receiver coupled to the antenna array for receiving the different summations of source signals, and a signal separation processor coupled to the receiver Processing by the signal separation processor includes creating a matrix based upon the different summations of source signals, with the matrix being defined by linear independent equations with fewer equations than unknowns. The matrix is underdetermined, and parameters associated with the matrix are modified based upon different sets of parameter values, and respective matrix quality factors associated with the different sets of parameter values are determined. The matrix is then biased with a preferred set of parameter values so that the solution space may be narrowed for obtaining a solution.

Each receiver operates based upon a respective channel code for de-spreading the desired and undesired signals for determining at least one desired signal associated with the respective channel code, and for combining the at least one desired signal and the undesired signals after the de-spreading. A processor is coupled to the receivers for forming a mixing matrix based upon the combined signals from each receiver, with entries on a diagonal of the mixing matrix corresponding to the desired signals and entries adjacent the diagonal corresponding to the undesired signals. The processor also processes the mixing matrix so that a level of the desired signals increases and a level of the undesired signals decreases.
