  • LOW-DENSITY PARITY-CHECK DECODER WITH SCALING TO REDUCE POWER CONSUMPTION
    Publication number: 20230403029
    Abstract: A method and apparatus are provided for decoding a plurality of codewords from a received binary bitstream. A first decoding stage processes each of the codewords with a first iterative decoding algorithm based on forward error-correction information of the codewords. A second decoding stage processes selected ones of the codewords with a second iterative decoding algorithm, which is based on forward error-correction information in the selected ones of the codewords. Each codeword selected for the second decoding stage is selected in response to an exit from the decoding of that codeword without the production of a decoded codeword. The second iterative decoding algorithm is configured to enable a greater number of iterations of decoding per codeword than the first iterative decoding algorithm.

  • Method and a node for detecting phase noise in MIMO communication systems
    Patent number: 9461773
    Abstract: A method for phase noise detection in a MIMO communication system comprises the step of computing an initial estimate of phase using received pilot symbols. A phase follows for interpolating between successive pilot symbol phase estimates to obtain a coarse resolution reference phase estimate. Then, it follows a phase for computing a fine resolution estimate of phase using said coarse resolution phase estimate together with data expressing characteristics of known phase noise processes, applying an expectation maximization (EM) algorithm. The application of the EM algorithm can be further refined using improved symbol decisions from a FEC decoding.
