  • Patent number: 8867673
    Abstract: A method for quantizing decision metrics (e.g., log likelihood ratios (LLRs)) for reduction of memory requirements in wireless communication is described. The method includes selecting a quantization algorithm. The quantization algorithm may be selected as a function of a characteristic of a decision metric representative of a transport block received over a communication channel, a characteristic of the transport block, or a condition of the communication channel. The method further includes quantizing the decision metric using the selected quantization algorithm to generate at least one quantized decision metric representative of the transport block. The method further includes storing the quantized decision metric and an indicia of the selected quantization algorithm to enable recovery of the decision metric representative of the transport block prior to decoding.

  • Patent number: 8824967
    Abstract: A method for interference reduction is described. The method is implemented in a wireless device. It is determined that a page is going to be received via a secondary receiver. It is also determined that a digital-to-analog converter (DAC) image from a transmitter will cause interference with the secondary receiver when the page is received. A sampling frequency of the DAC for the transmitter is changed so that there are not any DAC images from the transmitter that will cause interference with the secondary receiver.

  • Patent number: 8781043
    Abstract: Techniques for recovering a desired transmission in the presence of interfering transmissions are described. For successive equalization and cancellation (SEC), equalization is performed on a received signal to obtain an equalized signal for a first set of code channels. The first set may include all code channels for one sector, a subset of all code channels for one sector, multiple code channels for multiple sectors, etc. Data detection is then performed on the equalized signal to obtain a detected signal for the first set of code channels. A signal for the first set of code channels is reconstructed based on the detected signal. The reconstructed signal for the first set of code channels is then canceled from the received signal. Equalization, data detection, reconstruction, and cancellation are performed for at least one additional set of code channels in similar manner.
