Method for receiving wifi signals

Abstract

The present invention provides a method for receiving WIFI signals. The method includes using a wireless local area network path to transmit digital signals generated by a digital user device to an access point of a receiver. These signals include those from the bandwidth of certain user devices; and filters to change the position of the center frequencies of these user devices so that these signals combine the I and Q path ΔΣADC into a single composite ΔΣADC at a smaller sub-channel bandwidth, and select proper location of this center frequency and reduce its clock rate.
