Patent ID: 8842781

Claim:
A device, comprising: a delay profile estimator configured to estimate a delay profile of multiple paths of a radio signal, the delay profile indicating signal powers of the multiple paths as a function of time delay; and a path selector configured to select a path from the delay profile if the path has a signal power higher than a threshold, wherein the threshold comprises a first power threshold value which is valid in a first section of the delay profile and a second power threshold value which is valid in a second section of the delay profile, wherein the first power threshold value is greater than the second power threshold value, wherein the first section of the delay profile is valid for a first range of time delay values, and the second section of the delay profile is valid for a second range of time delay values different from the first range of time delay values, and wherein the first range of time delay and the second range of time delay do not overlap with respect to time delay, and wherein the second power threshold value is based on a signal power of a path having a largest signal power in the first section of the delay profile.
