METHOD AND APPARATUS FOR RECONSTRUCTING DESIRED SIGNAL IN CASE OF USING FULL DUPLEX RADIO (FDR) SCHEME |
摘要 |
The apparatus for reconstructing a desired signal using a full duplex radio (FDR) scheme includes: a digital self-interference cancellation unit configured to output a first digital signal; a demodulator configured to demodulate the first digital signal; a modulator configured to modulate the demodulated first digital signal; an attenuator configured to attenuate the modulated first digital signal by applying an attenuation coefficient to the modulated first digital signal; and an operation unit configured to receive the attenuated first digital signal and the first digital signal, and transmit a residual signal to the digital self-interference cancellation unit, wherein the residual signal is obtained by subtracting the attenuated first digital signal from the first digital signal. |

1. An apparatus for reconstructing a desired signal using a full duplex radio (FDR) scheme, comprising:
a digital self-interference cancellation unit configured to output a first digital signal; a demodulator configured to demodulate the first digital signal; a modulator configured to modulate the demodulated first digital signal; an attenuator configured to attenuate the modulated first digital signal by applying an attenuation coefficient to the modulated first digital signal; and an operation unit configured to receive the attenuated first digital signal and the first digital signal, and transmit a residual signal to the digital self-interference cancellation unit, wherein the residual signal is obtained by subtracting the attenuated first digital signal from the first digital signal, wherein the digital self-interference cancellation unit is configured to:
receive a second digital signal before digital-to-analog conversion (DAC) processing is performed in a digital to analog converter (DAC) of a transmitting end and a third digital signal obtained after analog to digital conversion (ADC) processing is performed in an analog to digital converter (ADC) of a receiving end,output a signal obtained after subtracting the second digital signal and the residual signal from the third digital signal. |
