Abstract
When an antenna receives a signal, the signal is inputted to delayers through a frequency converter, A/D converters, quadrature demodulators, filters and simultaneously is inputted to a MUX. The receiving signal inputted to the MUX is transmitted to an interference canceler panel, and the interference canceler panel generates both an interference replica signal and a symbol replica signal. The interference canceler panel demodulates the receiving signal for a channel corresponding to the symbol replica signal using both the interference and symbol replica signals. The interference replica signal generated by the interference canceler panel is transmitted to a transmitting/receiving panel and is inputted to interference elimination units. The interference elimination units eliminates interference components by subtracting the interference replica signal from the receiving signal delayed by the delayers and transmits the signal to a baseband signal processing panel.
