  • Patent number: 12143195
    Abstract: A communication receiver can determine an angle of arrival (AoA) of a communication signal. The communication receiver includes multiple receiving antennas and processing circuitry. The processing circuitry determines multiple phase shifts over multiple instances in time from first samples of a communication signal as observed by a reference receiving antenna selected from among the multiple receiving antennas, samples the communication signal as observed by the selected receiving antennas from among the multiple receiving antennas over the multiple instances in time to provide second samples of the communication signal, removes the multiple phase shifts from corresponding samples from among the second samples of the communication signal to provide phase corrected second samples of the communication signal, and determines the AoA of the communication signal from the phase corrected second samples of the communication signal.

  • Patent number: 6649492
    Abstract: A method for fabricating a strained Si based layer, devices manufactured in this layer, and electronic systems comprising such layers and devices are disclosed. The method comprises the steps of growing epitaxially a SiGe layer on a substrate, and creating a varying Ge concentration in this SiGe layer. The Ge concentration in the SiGe layer includes a unique Ge overshoot zone, where the Ge concentration is abruptly and significantly increased. The Si based layer is epitaxially deposited onto the SiGe layer, whereby is becomes tensilely strained. It is also disclosed that the strained Si based layer, typically Si or SiGe, can be transferred to a different bulk substrate, or to an insulator.
