  • Publication number: 20090296798
    Abstract: In one embodiment, an HSDPA co-processor for 3GPP Release 6 Category 8 (7.2 Mb/s) HSDPA that provides all chip-rate, symbol-rate, physical-channel, and transport-channel processing for HSDPA in 90 nm CMOS. The co-processor design is scalable to all HSDPA data rates up to 14 Mb/s. The coprocessor implements an Advanced Receiver based on an NLMS equalizer, supports RX diversity and TX diversity, and provides up to 6.4 dB better performance than a typical single-antenna rake receiver. Thus, 3GPP R6 HSDPA functionality can be added to a legacy R99 modem using an HSDPA co-processor consistent with embodiments of the present invention, at a reasonable incremental cost and power.

  • Patent number: 6798366
    Abstract: An architecture for a turbo decoder performs a faster max* computation. In this architecture, one or more lookup tables begin processing a digital signal prior to the most significant bit of the digital signal stabilizes. This technique allows processing in the lookup table to be accomplished during a period of time in which processing could not be accomplished previously. As a result, the architecture performs the max* computations at a faster rate than previous architectures.
