Patent ID: 8818419

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 location server, wherein: corresponding transmit diversity configurations are determined by said 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 location server; a signature function for said channel measurements for said mobile device, and said channel measurements at said scanned locations over said corresponding transmit diversity configurations, are selected by said location server; said signature function is utilized by said location server to determine said position estimate for said mobile device over said corresponding transmit diversity configurations; said position estimate for said mobile device is updated by said location server based on a resolution of said signature function over said scanned locations in said location scanning region; and said updated position estimate for said mobile device is calculated by said location server, by utilizing a different signature function for each of said channel measurements for said mobile device and said channel measurements with said scanned locations over said corresponding transmit diversity configurations.
