Correlation detection apparatus and CDMA receiving apparatus |
摘要 |
An apparatus for obtaining correlation by despreading a spread symbol with a spreading code is provided with a symbol storage section for storing symbol and a plurality of correlation calculators each of which executes a correlation calculation to obtain correlation by despreading the symbol data with a spreading code. The apparatus switches a spreading code to be provided to each of the plurality of correlation calculators individually so that each of the plurality of correlation calculators executes correlation calculation with a respective different spreading code and holds a same spreading code until correlation calculations of a plurality of symbols are finished.
