  • Method and apparatus for signal compression and decompression
    Patent number: 8923386
    Abstract: In one embodiment, the method of compressing a digital signal includes reducing redundancies in the digital signal, scaling a block of samples output from the reducing step by a scaling factor, and quantizing the scaled samples to produce compressed samples. The digital signal being compressed may be a digital radio frequency signal.
    Type: Grant

  • Conformal antenna array
    Patent number: 8594735
    Abstract: The present invention relates to a conformal antenna array. Embodiments of the present invention provide a transceiver for communicating data in a cell site of a wireless communication system. The transceiver includes the conformal antenna array including a plurality of antenna elements, where the plurality of antenna elements has a non-linear antenna configuration to occupy at least two dimensions, and a controller configured to transmit multiple beamforming signals using at least two same antenna elements of the plurality of antenna elements.

  • Antenna array for supporting multiple beam architectures
    Patent number: 8457698
    Abstract: The present invention relates to an antenna array for supporting multiple beam architectures. For example, a transceiver may include an antenna array. The antenna array includes a plurality of antenna elements, where the plurality of antenna elements is configured to support at least two beam architectures in a cell site. Each beam architecture is associated with a different configuration of sectors and beamforming signals. According to one embodiment, each beam architecture is associated with a different wireless standard. According to another embodiment, each beam architecture is associated with a different carrier within one wireless standard. The antenna elements may be arranged as a circular array.
