International Classification:

H04B007/00

US Classification:

342/367000

Abstract:

An antenna apparatus for increasing the capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective signal control component to provide a weight to the signal transmitted from each element. The weight for each antenna element is adjusted to achieve optimum reception during, for example, an idle mode when a pilot signal is received. The weight values cause the antenna array to create a beam former for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading and intercell interference are greatly reduced. The weights are adjusted at the transmitting site in accord with signal quality metric information determined at the receiving site. The signal quality metric information is returned to the transmitting site where the optimum signal quality metric is determined. The weights at the transmitting site are then set to provide the antenna directional angle represented by the optimum signal quality metric.

Abstract:

A single, common correlation filter (CF) core is provided in a receiver for recovery of data from received code division multiple access (CDMA) signals. Signals are received over CDMA channels with different data rates, where the received signals include user information such as pilot and data symbols that have been spread according to different despreading rates including tier 1, tier 2 and tier 3 rates, where tier 1 is the smallest despreading rate. The received signal is correlated at the smallest despreading rate in the correlation filter (CF) by time multiplexing delayed versions of the pseudorandom noise (PN) code. The correlated information is then demultiplexed and pilot-aided QPSK demodulated. The demodulated information is summed at the proper integer multiple of the tier 1 rate to achieve tier 2 and tier 3 despreading rates. According to an embodiment, the three strongest multipaths components in terms of the received power are selected in a window or time period for optimal information recovery.

Abstract:

A grabber having a pair of ice tong-like arcuate members is carried to the cean depths by a marine mammal to secure a hoisting line to an object on the bottom. A trigger mechanism is located on the grabber to assure precise positioning on and reliable engagement of the object.
