Abstract:
A receiving apparatus for receiving a signal that has been spectrum-spread with a spread code, comprising:a searcher for searching paths of signals received over multi-paths;a plurality of fingers for de-spreading the received signals received over the multi-paths and demodulating data contained therein; anda combiner for combining output data of said plurality of fingers,wherein said searcher includes:code generating means for generating a code having a phase that is successively shifted in a same pattern as the spread code that is used to spectrum-spread the signals being received;de-spreading means for multiplying the received signals received over the multi-paths by the code generated by said code generating means so as to de-spread each received signal to original data;correlation value detecting means for obtaining correlation values for individual phases designated by said code generating means with output data of said de-spreading means; andmaximum value detecting means for detecting a maximum value of the correlation values and storing the maximum value, andwherein the output data of said de-spreading means is demodulated with a phase corresponding to the maximum value stored in said maximum value detecting means.
