Abstract
A method in a node (110, 115) comprises generating (604) a plurality of constituent polar codes, each of the plurality of constituent polar codes having an associated block length and an associated set of information bits. The method comprises coupling (608) at least a portion of the sets of information bits associated with each of the plurality of constituent polar codes to generate a spatially coupled polar code. The method comprises encoding (612) a wireless transmission using the spatially coupled polar code.
Claims28
A method in a node, comprising:
- generating a plurality of constituent polar codes, each of the plurality of constituent polar codes having an associated block-length and an associated set of information bits;
- coupling at least a portion of the sets of information bits associated with each of the plurality of constituent polar codes to generate a spatially coupled polar code;
- and
- encoding a wireless transmission using the spatially coupled polar code.
A method in a node, comprising:
- receiving a wireless transmission encoded using a spatially coupled polar code, the spatially coupled polar code comprising a plurality of sets of information bits at least a portion of which have been coupled, each set of information bits associated with one of a plurality of constituent polar codes;
- and
- decoding the wireless transmission encoded using the spatially coupled polar code using feedforward decoding.
A node, comprising:
- processing circuitry, the processing circuitry configured to:
- generate a plurality of constituent polar codes, each of the plurality of constituent polar codes having an associated block length and an associated set of information bits;
- couple at least a portion of the sets of information bits associated with each of the plurality of constituent polar codes to generate a spatially coupled polar code;
- and
