Abstract
A method, an apparatus and a system for determining stress on a low density parity check (LDPC) process for a network using orthogonal frequency division multiplexing (OFDM).
Claims12
A computer-implemented method comprising:
- inputting, at a test instrument connected to a channel of a network transmitting signals using orthogonal frequency division multiplexing (OFDM), data received from the signals transmitted over the network, the received data comprising at least one parameter associated with a low density parity check (LDPC) process performed by the network for a profile of the channel;
- and
- determining an LDPC stress level for the profile based on the at least one parameter,
- wherein the at least one parameter comprises a number of received codewords on the profile and an LDPC iteration count for the profile and the LDPC stress level is determined an average LDPC iteration count per received codeword.

A test instrument configured to be connected to a channel of a network transmitting signals using orthogonal frequency division multiplexing (OFDM), said test instrument comprising:
- a storage device;
- and
- a processor executing program instructions stored in the storage device to:
- input data received from the signals transmitted over the network, the received data comprising at least one parameter associated with a low density parity check (LPDC) process performed by the network for a profile of the channel;
- and
- determine an LDPC stress level for the profile based on the at least one parameter,
- wherein the at least one parameter comprises a number of received codewords on the profile and an LDPC iteration count for the profile and the LDPC stress level is determined an average LDPC iteration count per received codeword.
