Abstract
A matched filter for use in a radio telephone receiver that receives Code Division Multiple Access (CDMA) signals. The matched filter produces precombinations of input values to significantly reduce the number of multiplication and addition operations, compared to conventional matched filters, required to produce a correlation value. This reduced number of required operations, along with a reduced number of delay elements required to despread CDMA signals, significantly reduces the overall power consumption of the matched filter. The use of such a matched filter in a device like a cellular phone, for example, would thus lead to longer battery life.
