  • Low-power code division multiple access receiver
    Patent number: 7248622
    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.
    Type: Grant
    Filed: July 11, 2003
    Date of Patent: July 24, 2007
    Assignees: STMIcroelectronics Asia Pacific Pte. Ltd., National University of Singapore
    Inventors: Karthik Sathiavageeswaran, Christopher A. Aldridge, Mohamed Imtiyaz Iqbal
