Low-power code division multiple access receiver

Abstract

A low-power receiver architecture of use in direct sequence spread spectrum communications system receivers, such as in a code division multiple access system, is provided. 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 filters is obviated. The low-power receiver architecture is also applicable as a front-end structure for multiple-mode receivers.
