Abstract: Disclosed is a method for analyzing the performance of a physical layer network coded system in a nakagami fading channel. The method analyzes the performance of a bidirectional relay system to which a physical layer network coding is applied and an average final symbol error rate in the nakagami fading channel. The present invention induces the upper limit of the average final symbol error rate with a closed formula by inducing the character of a gamma random variable which shows a probability character of the nakagami fading channel and applying the upper limit for a Gaussian function.

Abstract: PURPOSE: A variable optical microwave notch filter is provided to extract a plurality of signal factors by a single element by a variable method and extract the signal factor in an optical base, thereby providing a method capable of extracting even when the frequency of a carrier is high, when using a plurality of signal carriers in order to receive a plurality of sensors. CONSTITUTION: A variable optical microwave notch filter has a property of obtaining a stable filtering characteristic regardless of the time delay of the reflective optical amplifier which is an incoherent source, and the length of the optical source coherence. The optical source becomes locked by auto-injection by a cavity which is generated between an RSOA(Reflective Optical Amplifier) and an FBG(Fiber optical Bragg Grating), and an oscillation wavelength of the RSOA, which is locked by auto-injection, is decided by a peak wavelength of the FBG.
