Abstract: 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.

Abstract: 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.

Abstract: 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 (?i) 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.

Abstract: 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.
