  • Publication number: 20160157222
    Abstract: A joint user detection apparatus for a wireless communication system, such as OFDM systems, arranged to account for timing impairments experienced by CAZAC codes. The proposed apparatus brings improvements over conventional receiving apparatuses by allowing joint user channel estimation processing and joint user equalization processing while considering timing impairments of user associated information present within a symbol of a received signal. The proposed solution could be used on conventional receiving apparatuses since both joint user channel estimation processing and joint user equalization processing can be activated independently such that either one or both improvements may be activated as needed or as required by the design of the conventional receiving apparatuses. A method and a computer program are also claimed.

  • Patent number: 9353017
    Abstract: A method of trimming a current source in an IC includes deriving a reference voltage from an external supply, and developing a measurement voltage across an external reference resistance receiving the current to be trimmed. An on-chip ADC is used to provide corresponding digital reference and digital measurement signals. A digital comparator compares the digital signals and provides a digital trim signal, which is used to adjust the current to be trimmed until the digital measurement signal is equal to the digital reference signal within an acceptable tolerance. Gain and offset errors in the ADC cancel and do not affect the calibration of the trim operation.

  • Patent number: 9355691
    Abstract: A system provides synchronous read data sampling between a memory and a memory controller, which includes an asynchronous FIFO buffer and which outputs a clock and other control signals. An outbound control signal (e.g., read_enable) is used to time-stamp the beginning of a read access using a clock edge counter. The incoming read data is qualified based on the time-stamped value of the read_enable signal plus typical access latency by counting FIFO pops. The system performs correct data sampling irrespective of propagation delays between the controller and memory. The system may be implemented in a System on a Chip (SOC) device having a synchronous communication system.

  • Patent number: 9356577
    Abstract: Receivers for memory interfaces and related methods are disclosed having pulsed control of input signal attenuation networks. Embodiments include a DC common mode attenuation network, an AC coupling network, a pulse generator, and an amplifier. The pulse generator receives the output of the amplifier and generates a pulse signal that in part controls the operation of the attenuation network. The attenuation network generates an attenuated signal having reduced DC common mode levels. This attenuated signal is combined with an AC component passed by the AC coupling network. The resulting combined signal is detected and amplified by the amplifier. Different voltage domains are used for the attenuation network and the AC coupling network as compared to the amplifier and the pulse generator. By attenuating DC common mode levels while maintaining AC signal levels, the disclosed embodiments allow for proper signal detection over a wide range of DC common mode levels.

  • Patent number: 9356652
    Abstract: An electronic device is provided for determining a hopset for a frequency hopping radio communication system. The hopset is a number of radio channels in a range of channels available for radio communication, and other channels in the range constituting a channel pool of pool channels. A hopset processor assesses quality of the radio channels for communication, and removes a channel from the hopset when the assessed quality is below a predetermined threshold. A probability set is provided, the probability set having probability values for respective radio channels in the range, which probability values are adapted based on the assessed quality in the respective radio channels. A replacement channel is selected in a pseudorandom way from the channel pool weighted by the probability values, and then added to the hopset. Due to the pseudorandom selection of channels for the hopset the system can efficiently cope with various interferences.

  • Publication number: 20160149596
    Abstract: A turbo decoder stores received data in words in systematic memory and parity memory in a way that is known that it will be used for later iterations by turbo decoder engines arranged to operate in parallel. A loader receives and separates LLRs into systematic and parity data and stores them into a portion of a word per cycle until a word is full in a corresponding one of the systematic memory and parity memory. The turbo decoder engines read the LLRs from one word of the systematic memory and one word of the parity memory in a single cycle. The data can be rearranged within the words in an order format for the turbo decoder engines to later read them by providing sub-words corresponding to respective ones of the plurality of turbo decoder engines.
