Abstract: A rake receiver comprises a plurality of receive antennas and a processing system. Each receive antenna has a plurality of demodulation elements. The processing system is configured to assign a plurality of demodulation elements from a plurality of receive antennas to a multipath group, assign the multipath group to a multipath signal, and independently adjust a time delay value of each demodulation element in the multipath group to correspond to a local time delay of the multipath signal at the corresponding receive antenna.

Abstract: A wireless communication device can include an antenna to transduce signals at first and second spectral bandwidths to electrical signals, sampler circuitry to receive the electrical signals and produce samples of the electrical signals at a specified sample rate, a first radio access technology (RAT) detector to determine whether a first synchronization signal (SS) of a first RAT is present in the samples, a second RAT detector in parallel with the first RAT, the second RAT detector to determine whether a second SS of a second RAT is present in the samples, and controller circuitry to adjust a spectral bandwidth of the of the antenna and the specified sample rate of the sampler circuitry based on signals from the first RAT detector and the second RAT detector indicating whether the first SS and the second SS are present in the samples, respectively.
