MT LDPC Generate Regular Parity Check Matrix (G Dataflow)

Version:
    Last Modified: February 7, 2018

    Generates a regular parity check matrix that is used by MT LDPC Encoder for LDPC encoding. In this node, the number of ones in each column and the number of ones in each row are kept constant.

    n

    The number of columns in the parity check matrix.

    Default: 12

    datatype_icon

    j

    The number of ones in the columns of LDPC code. j must be an odd number.

    Default: 3

    datatype_icon

    k

    The number of ones in the rows of LDPC code.

    Default: 0

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    maximum number of iterations

    The maximum number of iterations to return a parity check matrix that is not rank deficient.

    Default: 30

    datatype_icon

    regular parity check matrix

    The regular parity check matrix generated by this node.

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
