MULTIPATH MITIGATION IN POSITIONING SYSTEMS

WIPO Patent Application WO/2013/032285

A2

An apparatus for receiving positioning signals comprises an antenna configured to output a plurality of antenna signals and a multipath compensation module for detecting multipath interference, and if multipath interference is detected, selecting one or more of the antenna signals and combining the selected one or more antenna signals to obtain a compensated signal. The antenna is arranged to distinguish between ones of the positioning signals received at different incident angles, and each antenna signal includes ones of the positioning signals received in a predetermined range of incident angles. The multipath compensation module may determine whether multipath interference is present in each antenna signal, and may not select any antenna signals which include interference when selecting the antenna signals to be combined. The gain of each antenna signal may be adjusted before the signals are combined, to maintain the noise power of each antenna signal below a predetermined limit. The phase of each antenna signal may be adjusted before the signals are combined, to reduce phase differences between the antenna signals.
