Abstract: A low-power receiver architecture of use in direct sequence spread spectrum communications system receivers, such as in a code division multiple access (CDMA) system. The receiver employs analog correlation, wherein its analog-digital converters are able to operate at the system symbol rate, and the requirement for finite impulse response (FIR) filters is obviated. The low power receiver architecture is also applicable as a front-end structure for multiple-mode receivers.
