摘要： The present invention relates to a device for compensating a radio frequency distortion caused by a sample/hold operation of a digital/analog converter in an orthogonal frequency division multiplexing (OFDM) transmission system, and a method thereof. In a digital transmission system, an edge frequency signal of a transmission signal band is distorted by a sample/hold operation of a digital/analog converter such that a signal attenuation is generated at a frequency domain by a sync function having a zero point at a sample frequency of a transmission signal. In the present invention, the signal distortion may be compensated by multiplying a coefficient of an inverse sync function by a signal weight value at the frequency domain, and it may be compensated by using a single multiplier and a lookup table storing the coefficient of the inverse sync function.

摘要： The present invention relates to a wireless transceiver system for supporting a dual mode that simultaneously supports the Frequency Division Duplex (FDD) method and the Time Division Duplex (TDD) method in a certain frequency band. The present system supports the FDD system conducting transmission and reception simultaneously by using different frequency bands for transmission and reception as well as the TDD system temporally alternating transmission and reception by using the common frequency band among an upper frequency band and a lower frequency band used in the FDD system as well as another frequency band adjacent thereto, thereby selectively supporting both of the two communication systems in a wireless transceiver system.

摘要： A receiver is protected by reducing a transmit leakage signal leaked when a transmit signal is radiated through the antenna by using three circulators (transmitter, antenna, and receiver). The transmitter and antenna circulators output the transmit leakage signal to be reduced to less than the transmit signal through a first leakage path. The transmitter and receiver circulators output the transmit leakage signal through a third leakage path and reduce the signal. The transmit leakage signals received through the first and third leakage paths are canceled, and that received through a second leakage path is output to a receiver. The transmit leakage signal has a 40 dB signal reduction compared to the transmit signal, and is transmitted to the receiver.
