摘要： A wireless system, which minimizes nulls within the wireless system, while simultaneously providing diversity. A wireless system will now have increased capacity and coverage due to an enhanced signal to interference ratio in the areas of beam overlap. The system uses time or frequency offset on the signals input to an antenna to minimize interference in the regions of beam overlap. Additionally, polarization diversity can be introduced using Butler Matrices in conjunction with array elements to enhance the interference reduction.

摘要： A receiver (200) is provided receiving signals from differing base stations (BTSA and BTSB). The signal from BTSA is encoded using a first rate convolutional encoder while the signal transmitted from BTSB is encoded using a second rate convolutional encoder. Since the multiple base station links may result in a different number of symbols being received for each bit transmitted, the symbols received for each link cannot be simply combined. Therefore, in the preferred embodiment of the present invention, the resulting symbols are passed to multiple branch metric circuits (210–211), where branch metrics (μi) for the symbols are obtained. After the ith branch metrics for the base stations are computed, the branch metrics for each base station are passed to a combiner (212) where they are combined.

摘要： Methods and systems are provided for transmission power control in a multiple access communication system, providing power ramping of a noise floor power level in advance of a high data rate transmission, at a comparatively higher power level, by a mobile station. The preferred method includes receiving a request at a base transceiver station (BTS) for a data transmission by a first mobile station of a plurality of mobile stations (300), the data transmission to have a predetermined data transmission power level; measuring a noise floor power level (305); and comparing the measured noise floor power level to the predetermined data transmission power level (310). When the measured noise floor power level is less than the predetermined data transmission power level, the BTS schedules the data transmission from the first mobile station to occur following the power ramping of the noise floor, and directs the plurality of mobile stations to incrementally increase their transmit power levels to ramp the noise floor power level. Other methodologies to ramp the noise floor power level include injecting analog or simulated noise into the receive path of BTS, or directing the mobile station to transmit meaningless data at increasing power levels prior to transmission of requested data.

摘要： A base station subsystem includes at least one transmit branch having a forward path that includes a signal processing unit coupled at an input to an input Fourier Transform Matrix (FTM) and at an output to an output FTM. The transmit branch further includes two error compensation loops, an inner feedback loop and an outer feedback loop. The inner feedback loop provides error compensation for error introduced by the signal processing section to a signal input to the transmit branch. The outer loop provides error compensation for all residual error introduced into the signal when routed through the transmit branch forward path after error compensation may be performed by the inner feedback loop.

摘要： In the present technique of data transmission management provided, a composite status indicator value is assessed (716) based on multiple channel quality indicator reports over a predefined time. The assessed composite status indicator value is compared (718) to a first threshold value. If the assessed composite status indicator value does not correspond in at least a predetermined way to the first threshold value, the mobile station is classified (720) in a high speed data region. Otherwise, the assessed composite status indicator value is further compared (726) to a second threshold, and if it corresponds in at least a predetermined way to the second threshold, the mobile station is classified (734) in the low speed data region.

摘要： A communication device converts a bit stream to multiple symbols and provides encryption at a physical layer by shifting a phase of each symbol of the multiple symbols to produce multiple encrypted symbols. Each encrypted symbol of the multiple encrypted symbols is modulated with an orthogonal subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted via a wireless link. On a receive side, a receiving communication device receives the transmitted, encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase used to encrypt the symbol at the transmit side.
