  • Correlator/FIR filter unit for dual-mode transceiver
    Patent number: 6748014
    Abstract: A Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) transceiver in which correlator banks consisting of an array of dual-code correlators (two tri-code correlators) are used to form correlator filters, such as chip matched filters or multi-code RAKE receivers, or FIR filters for CDMA/TDMA related applications.

  • Methods and apparatus to despread dual codes for CDMA systems
    Patent number: 6724838
    Abstract: A correlator and matched filter for use with coded transmission, such as CDMA, form new codes from the sums and differences of the original codes, where only one of the new codes is non-zero for each element position and effect hardware savings using the new codes.

  • Correlator for CDMA applications
    Patent number: 6370208
    Abstract: Correlators categorize different combinations of code sequences and identify locations for which code elements for the code sequences are equivalent. Then, a dispreading operation is performed once for each equivalent combination. The equivalent combinations, for example, may be locations where the code elements are the same or locations where code elements are complements of one another.
