Abstract:
Radio equipment adopting a code division multiple access method, comprising:a transmitting/receiving panel receiving a signal from an antenna, performing a prescribed process for the receiving signal, outputting the receiving signal and simultaneously delaying the signal by a prescribed time; a removable baseband signal processing panel inversely diffusing/demodulating the receiving signal transmitted from the transmitting/receiving panel and demodulating data; and a removable interference canceler panel generating an interference replica signal to be used to eliminate interference components included in the receiving signal, based on the signal received from the transmitting/receiving panel and returning the interference replica signal to the transmitting/receiving panel, wherein the transmitting/receiving panel eliminates interference components by subtracting the interference replica signal transmitted from the interference canceler panel from the delayed receiving signal, inputs the receiving signal after interference elimination to the baseband signal processing panel and enables the baseband signal processing panel to demodulate data based on the receiving signal after the interference elimination, and said transmitting/receiving panel is provided with a selector for switching a transmission system route of the receiving signal to said baseband signal processing panel in such a manner that the receiving signal is transmitted to said baseband signal processing panel without the delay even if said interference canceler panel is removed.
