The present disclosure concerns receivers for use in nodes or devices that participate in wireless communications. In one exemplary embodiment, the receiver receives a first signal attributable to a first carrier and a second signal attributable to a second carrier. A first path searcher detects taps in the first signal attributable to the first carrier. A second path searcher detects taps in the second signal attributable to the second carrier. A channel tap selector selects, based on received energy values for taps detected by the first path searcher and the second path searcher, which tap values are to be used for taps of the receiver for both the first carrier and the second carrier.

Apparatus and method for jointly selecting the tap values and delays of the fingers for a rake receiver of two carriers

A communication node () with is arranged to receive signals from at least one antenna (). A frequency domain conversion is executed () for two or more antenna signals by receiving () a continuous signal from one of the at least one antenna (), splitting () the continuous antenna signal into windowed signals, and performing () a frequency domain conversion of the windowed signals. Then, a channel estimate based on a frequency converted pilot signal is provided () by extracting () a pilot signal, splitting () the pilot signal into windowed signals, performing () a frequency domain conversion of the split pilot signal; and providing () a channel estimate of the frequency converted pilot signal. Diversity combined signals are provided () by performing () diversity combining based on the frequency converted windowed signals and the channel estimate, and by combining () the diversity combined signals.
