Abstract:
1. A CDMA wireless base station that performs a channel allocation based on parameters externally received, characterized by comprising: a preamble detection and path search section adapted to perform a preamble detection in a reception base band signal or perform a path search of the reception base band signal; demodulating means for demodulating the reception base band signal; and controlling means for controlling said preamble detection and path search section so as to function either as a preamble detection section or as a path search section, wherein said preamble detection and path search section comprises a plurality of matched filters, in the event that said controlling means controlling said preamble detection and path search section to function as the preamble detection section said plurality of matched filters being connected serially, and in the event that said controlling means controlling said preamble detection and path search section to function as the path search section said plurality of matched filters are each used to acquire different channel from other.
