Abstract: An apparatus and method for passive radio frequency identification (RFID) reader digital demodulation with respect to a Manchester subcarrier signal are disclosed. In a passive RFID environment where the Manchester subcarrier signal contains DC components in a frequency region, even when a tag signal containing the DC offset noise is input to a baseband, demodulation may be efficiently performed while the DC offset noise is removed. Therefore, accurate detection of tag information from the tag signal may be achieved.

Abstract: The present invention relates to an optical communication, and more particularly, to a wideband wavelength division multiplexing (WDM) optical communication system which can have a broad amplification band while overcoming a polarization dependency and solving a signal leakage between channels. In an optical amplifier module and optical transmission system for a WDM optical communication system using this, the optical amplifier module uses a semiconductor quantum dot optical amplifier as an amplifying means, and thus has a wide amplification bard and has no a polarization dependency of a gain and a signal leakage between channels, and the optical transmision system uses a semiconductor quantum dot optical amplifier module when several optical amplifier modules are connected for use so that a gain automatically becomes flat and automatically becomes fixed even though a channel number and an input signal size become different. Accordingly, the semiconductor quantum dot optical amplifier module of the present invention can be used as a repeater, an amplifier of a metro WDM system, and an amplifying means for the other systems of a WDM type. The optical transmission system using the semiconductor quantum dot optical amplifier module of the present invention can be used in a long-distance transmission system of a WDM type and a WDM network which pass through the optical amplifier module several times.

Abstract: A passive phase jitter modulation (PJM) tag is charged with power in a continuous wave (CW) section. When receiving a command from a reader, the passive PJM tag must recognize the command and determine exactly when to begin demodulating the command. Only then can the passive PJM tag demodulate the command. To this end, a synchronization apparatus for accurately demodulating a signal input to a PJM tag includes a plurality of correlators correlating a received phase jitter-modulated signal with a template of an internal matched filter which is in the same form as at least a portion of a modified frequency modulation (MFM) flag.
