摘要:
A controllable equalizer is arranged to be automatically and selectively disabled and is configured to operate in a frequency modulated (FM) radio receiver. The controllable equalizer includes an equalizer (115) that is configured to perform an equalization algorithm, e.g., CMA, that relies on a predetermined distribution for a received signal, where the received signal is available from the FM radio receiver and a spurious signal detector (123) that is configured to determine whether a spurious signal is present in the received signal and to disable the equalizer when the spurious signal is present. A method (300) of automatically and selectively disabling an equalizer operating in a frequency modulated (FM) radio receiver includes performing an equalization algorithm (307) on an FM received signal, the equalization algorithm relying on a predetermined distribution of the FM received signal, determining whether a spurious signal is present (309) in the FM received signal; and disabling the equalizer (317) when the spurious signal is present in the FM received signal.
摘要:
Highly ordered and aligned epitaxy of III-Nitride nanowires is demonstrated in this work. M-axis is identified as a preferential nanowire growth direction through a detailed study of GaN/AlN trunk/branch nanostructures by transmission electron microscopy. Crystallographic selectivity can be used to achieve spatial and orientational control of nanowire growth. Vertically aligned (Al)GaN nanowires are prepared on M-plane AlN substrates. Horizontally ordered nanowires, extending from the M-plane sidewalls of GaN hexagonal mesas or islands demonstrate new opportunities for self-aligned nanowire devices, interconnects, and networks.
