<p>PROBLEM TO BE SOLVED: To provide a communication system which suppresses increase of device scale due to providing an interference suppress function in a radio base station device, prevents decrease in channel use efficiency and uses low-cost code division multiple access making it possible to perform high quality communication. SOLUTION: A signal subjected to interference cancel stage processing is processed by the stage of a subsequent cascaded stage in a conventional manner. Interference cancel stage processing is performed by cascading circuits performing the same processing in a multistage interference canceler device in several stages, producing a replica signal by performing demodulation of a signal subjected to interference cancel stage processing, subsequently making the signal feedback to a correlation circuit to perform demodulation again and repeating the same signal processing. Hardware quantity is reduced by adopting such a configuration.</p> |
