Title:
Conversion of the signal which Pre-coding (ed) for wireless communication
Document Type and Number:
Japanese Patent JP6023315
Kind Code:
B2
Abstract:
Embodiments of the claimed subject matter provide a method and apparatus for transforming signals for wireless communication. One embodiment of the apparatus includes a transformer comprising a plurality of first ports and second ports. Each first port is associated with a mode of a first antenna array configuration and each second port is configurable to be communicatively coupled to one of the antennas deployed in the first antenna array configuration. This embodiment also includes a selector configurable to select a subset of the modes of the first antenna array configuration based on a degree of variation with azimuth. This embodiment further includes a mapper configured to map each of a plurality of third ports to one of the first ports associated with one of the subset of modes. Each of the third ports is associated with a mode of a second antenna array configuration.
