摘要： A method for removing selected signals from a received signal prior to decoding begins by receiving communication signals from a transmitter over a CDMA air interface. The received communication signals are input to a traffic signal cancellation system for canceling unwanted traffic signals, thereby producing an output (O). The received communication signals are input to a pilot signal cancellation system for removing a global pilot signal, thereby producing an output (Oadd). The output (Oadd) of the pilot signal cancellation system is subtracted from the output (O) of the traffic signal cancellation system to provide a cancellation system output.

摘要： A method implemented in a communication device for tracking a spread spectrum signal having an associated code at a receiver is claimed. Components of the spread spectrum signal are despread using locally generated versions of the associated code, each component having a different code phase. A tracking error is determined based on a quadratic function of the components and a weighting factor relating the signal to the tracking error. The weighting factor is a function of a time shift. A minimum in the tracking error is determined by adjusting the time shift.

摘要： A method and apparatus for transmitting data in code division multiple access communications. The method includes processing spread first data with a channel response matrix using an equalization circuit to pre-equalize the spread data to compensate for a channel response prior to transmission. The pre-equalized data is received and recovered by a receiver. Second data, transmitted from the receiver, is received and recovered using the equalization circuit to equalize the second data to compensate for a channel response that the first data encountered.

摘要： The present invention is related to a method and apparatus for implementing space frequency block coding (SFBC) in an orthogonal frequency division multiplexing (OFDM) wireless communication system. The present invention is applicable to both a closed loop mode and an open loop mode. In the closed loop mode, power loading and eigen-beamforming are performed based on channel state information (CSI). A channel coded data stream is multiplexed into two or more data streams. Power loading is performed based on the CSI on each of the multiplexed data streams. SFBC encoding is performed on the data streams for each of the paired subcarriers. Then, eigen-beamforming is performed based on the CSI to distribute eigenbeams to multiple transmit antennas. The power loading may be performed on two or more SFBC encoding blocks or on each eigenmodes. Additionally, the power loading may be performed across subcarriers or subcarrier groups for weak eigenmodes.

摘要： A receiver receives signals and noise over a frequency spectrum of a desired received signal. The desired received signal is spread using code division multiple access. The received signals and noise are demodulated to produce a demodulated signal. The demodulated signal is despread using a code uncorrelated with a code associated with the desired received signal. A power level of the despread demodulated signal is measured as an estimate of the noise level of the frequency spectrum.

摘要： Implementation of communication in a multi-protocol wireless network communication network is performed according to protocols independently selected for forward and reverse communication links. A communication request is made according to predetermined criteria, and a communication link is established responsive to the request. A determination is made of a preferred communication protocol in at least one direction (forward or reverse link). The communication link is established for that direction in accordance with the preferred communication protocol while controlling communication in the other direction independently.

摘要： A multicellular communications system where transmission between a roving subscriber and multiple base station transceivers is maintained throughout the territory. Each mobile subscriber unit has global code seeds for the entire communications system or an updated neighbor list and continuously searches to access available cell base stations while maintaining a communication link with one base station. Candidate cell base stations are interrogated and communicated with. The candidate base station that requires less transmitting energy from the mobile subscriber unit is closely monitored. When the mobile subscriber unit can successfully communicate with less transmit power than currently required by the present base station, the mobile subscriber unit is handed off to the candidate base station transceiver.
