Abstract  Abstract

A base station apparatus comprising a transmission/reception amplifying unit for amplifying CDMA signals from/to a mobile station; a radio unit connected to the transmission/reception amplifying unit for D-A converting a base band-spread transmission signal to an analog signal quadrature-modulating the analog signal quasi-synchronously detecting a received signal and A-D converting the detected signal to a digital signal; a base band signal processing unit connected to the radio unit and subjects the transmission signal and the received signal to the base band signal processing; a transmission channel interface connected to the base band signal processing unit and serving as an interface with an external line; and a base station control unit that controls radio circuits and setting/resetting of the radio circuits. The apparatus effects communication with an external line by using ATM cells. The communication with the mobile station by using CDMA signals is effected by mapping a plurality of logic channels on a plurality of physical channels. The band of the CDMA signals is spread with two short and long spread-series codes.
