Abstract: Presented herein are techniques for suppressing electrical interference caused by a feedback path(s) between an output channel and an input channel of an implantable medical device. In particular, the output channel carries stimulation signals that can pass through the feedback path(s) and appear in the input channel, thereby causing interference with any input signals carried by the input channel. The implantable medical device is configured to determine characteristics of the feedback and subsequently use the feedback characteristics to generate feedback compensation signals for application to the input channel.

Abstract: A method of operating a communications circuit with at least one control channel and at least one data channel includes the steps of monitoring the at least one control channel, powering a receiver portion of the circuit when the at least one control channel indicates that data is to be received, and refraining from powering the receiver portion when the at least one control channel indicates that data is not to be received. The circuit can operate, for example, under the 3GPP HSDPA standard. Where desired, the clock and power supply to the receiver portion and a bit rate processing portion can be independently gated.

Abstract: In one embodiment, a receiver including one or more signal-processing blocks and a hardware-based matrix co-processor. The one or more signal-processing blocks are adapted to generate a processed signal from a received signal. The hardware-based matrix co-processor includes two or more different matrix-computation engines, each adapted to perform a different matrix computation, and one or more shared hardware-computation units, each adapted to perform a mathematical operation. At least one signal-processing block is adapted to offload matrix-based signal processing to the hardware-based matrix co-processor. Each of the two or more different matrix-computation engines is adapted to offload the same type of mathematical processing to at least one of the one or more shared hardware-computation units.

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.
