ABSTRACT:
Disclosed is a W-CDMA wireless base station adapted to meet various specifications over a wide range to dynamically change the allocated numbers of RACH's and DPCH's depending on a cell radius and the number of Signatures. The W-CDMA wireless base station that performs an optimal channel allocation based on parameters received from an external network, comprises: a preamble detection and path search section adapted to perform an RACH preamble detection in a reception base band signal or perform a path search of the reception base band signal; demodulation section adapted to demodulate the reception base band signal by including therein a plurality of fingers and combining outputs of the fingers; a control section adapted to control said preamble detection and path search section to switch itself either to a preamble detection section or to a path search section so as to change the allocated numbers of RACH's and DPCH's based on the parameters.
