    Abstract: A linear coverage area antenna system for use within a CDMA communication system is disclosed herein. In a preferred implementation, two linear coverage area antenna structures (210', 212') are positioned in parallel and coupled to a base station (200'). Within the base station (200'), a transmitter (220') generates remote user directed spread spectrum signals, these signals being provided to the first and second linear coverage area antenna structures (210', 212') through an antenna interface. The antenna interface includes a time delay element (292) for introducing a predetermined time delay between components of the remote user directed spread spectrum signals transmitted by the first and second linear coverage area antenna structures (210', 212'), respectively. The base station (220') also further includes at least a first demodulation element (510A) for demodulating an aggregate spread spectrum signal comprised of a plurality of system user directed spread spectrum signals received by the first linear coverage area antenna structure (210') and a second demodulation element (515A) for demodulating a second aggregate spread spectrum signal comprised of a plurality of system user directed spread spectrum signals received by the second linear coverage area antenna structure (212').

    Abstract: A method and apparatus for transmitting voice and data in a code division multiple access (CDMA) wireless telecommunications system is described. In an exemplary embodiment of the invention, a base station transmits voice information at a voice transmit power and data at a data transmit power that is equal to a maximum transmit power minus the voice transmit power. In a preferred embodiment of the invention, each base station reports the voice transmit power to a base station controller in 20 ms intervals. The base station controller responds by calculating an available data transmit capacity, and by forwarding data to each base station equal to the available data transmit capacity. Each base station then transmits all voice data at the current voice transmit power, and data at the current data transmission power. If the amount of data received exceeds the capacity provided by the current data transmission power, some data is not transmitted. The base station then notifies the base station controller if data was not transmitted, and the base station controller attempts to retransmit the data at a later time.

    Abstract: A system and method for adaptively sectorizing channel resources within a digital cellular communication system is disclosed herein. The system includes an antenna arrangement for providing at least first and second electromagnetic beams for receiving a first information signal transmitted by a specific one of a plurality of users, thereby generating first and second received signals. A first set of beam-forming signals are then generated from the first and second received signals. A demodulating receiver is provided for demodulating at least first and second beam-forming signals included within the first set of beam-forming signals, thereby producing first and second demodulated signals. The system further includes a tracking network for tracking multipath information signals, received from various positions and angles of incidence, based on comparison of the first and second demodulated signals.
