Abstract: A receiver and a method are applied in a wireless communication system for detecting interference with a coexisting radar system. A signal received from an antenna is fed through an analog part and a subsequent digital part of said receiver. The receiver has an element with a-priori known attenuation values for a predefined set of frequencies, a first branch-off element for deriving a first detection signal from the signal before the element and a second branch-off element for deriving a second detection signal from the signal after the element. The receiver processes the first and the second detection signal such that a difference between the first and second detection signal is comparable with a threshold value, where the threshold value depends on the a-priori known attenuation values of the element. Depending on the comparison result, a frequency is identified as interfering or not a co-existing radar system.

Abstract: A light emitting device and a method for fabricating the same according to the present invention are advantageous in that since an LLO (Laser Lift Off) process is performed using a thick metal film grown through a growth process, an occurrence rate of a void is remarkably decreased due to dense bonding between metals so that an occurrence rate of a crack can be decreased.  Further, the present invention has an advantage in that a metal is filled in trench regions formed through an isolation process for devices, thereby protecting the devices and ensuring excellent heat dissipation.  The present invention has a further advantage in that a reflective film is formed on inclined sidewalls of a device-forming thin film layer so that light loss through lateral sides of the device can be reduced, thereby improving optical properties.
