Base station device

Abstract

A base station device capable of easily conducting large-scale searches for a number of channels by execution of software is provided. A first filtering section filters reception data to which FFT has been applied by multiplying the reception data by rectangular wave window. A second FFT section applies FFT to respective codes stored in a code storage section. A multiplication section calculates correlation values by multiplying the reception data after FFT by the codes after FFT. A second filtering section filters the calculated correlation values by multiplying the correlation values by Hamming window. An averaging section averages the filtered data. An IFFT section applies IFFT to the averaged data to produce a delay profile. A path search section searches respective paths of the channels based on delay profiles produced for each of the different channels.
