Method of and system for estimating a time of arrival of a radio signal

A method in a mobile wireless communication device, comprising:

• receiving a plurality of radio signals at the mobile wireless communication device;
• estimating a time of arrival for each of the plurality of radio signals received at the mobile wireless communication device;
• selecting a subset of the plurality of the radio signals received at the mobile wireless communication device based on the time of arrival estimates;
• generating an averaged propagation channel estimate from the subset of radio signals;
• and
• estimating an averaged time of arrival from the averaged propagation channel estimate.

A mobile wireless communication device, comprising:

• a receiver;
• processor coupled to the receiver,
• the processor having means for means for estimating a time of arrival for each of a plurality of the radio signals received by the receiver,
• the processor having means for selecting a subset of the plurality of the radio signals received by the receiver in response to the time of arrival estimates,
• the processor having means for generating an averaged propagation channel estimate from the subset of radio signals, and
• the processor having means for estimating an averaged time of arrival from the averaged propagation channel estimate.
