A signal is received from a mobile device as multiple data samples. The received signal includes a first component corresponding to a known reference signal and a second component corresponding to an unknown channel impairment or an unknown noise. A sequence of blocks is formed based on the received samples. The first component of the received signal corresponding to the reference signal is known to within a constant phase shift over each block. A plurality of function values are generated as a function of time, frequency, and phase, based on the received signal, corresponding to a plurality of times, a plurality of frequencies, and a plurality of phase sequences. A time, a frequency, and a phase sequence corresponding to an optimal value the function values are determined. The determined time is outputted as a time of arrival of the received signal.

System and method for sub-coherent integration for geo-location using weak or intermittent signals

A system and method for a network analysis system operating in a wireless communication system with repeaters is disclosed. Embodiments of the system and method enable the network analysis system to determine if signals being received by the network receivers arrive directly from a target mobile appliance or if the signals are passing through a repeater. The repeaters, through an augmentation, measure attributes of a received signal and based on these attributes the system determine whether the signal is served by a repeater or other network device.
