Patent ID: 8639270

Claim:
A method of processing signals, the method comprising: in a mobile device: receiving radio frequency signals from one or more base stations, wherein: each of said one or more base stations comprises a plurality of distributed transceivers; and each of said plurality of distributed transceivers comprises an independently configurable antenna array for transmitting said radio frequency signals to said mobile device; generating channel measurements for said received radio frequency signals; and receiving a position estimate for said mobile device from a remote location server, wherein: corresponding transmit diversity configurations are determined by said remote location server, said corresponding transmit diversity configurations being applied to said one or more base stations for both said channel measurements for said mobile device and channel measurements at scanned locations in a location scanning region; said position estimate for said mobile device over said location scanning region utilizing said channel measurements for said mobile device, said channel measurements at said scanned locations, and said corresponding transmit diversity configurations are calculated by said remote location server; and wherein said corresponding transmit diversity configurations comprise base station identifier index, transceiver index, transceiver operating frequency, and transmit antenna patterns and array configurations for each of said one or more base stations.
