Impulse noise diagnosis during retransmission

摘要

Disclosed and recited herein are devices, systems, methods, and programs by which data is transmitted and, when receipt of the transmitted data has not been acknowledged, an impulse noise occurrence may be diagnosed at the transmitter based on flag streams associated with data transfer units corresponding to the transmitted data. Characteristics of the impulse noise occurrence may be diagnosed based on, at least, a number of consecutive error bits in at least one of the flag streams associated with the data transfer units corresponding to the transmitted data.

主权项

1. A method, comprising:
transmitting data in data transfer units; determining that receipt of the transmitted data has not been acknowledged based on a lack of acknowledgements for one or more of the data transfer units corresponding to the transmitted data; determining an impulse noise occurrence based on a flag stream associated with the data transfer units, the flag stream comprising, for each of the data transfer units, a flag representing an acknowledgement status of the corresponding data transfer unit; diagnosing characteristics of the impulse noise occurrence based on, at least, a number of consecutive error bits in the flag stream, the error bits being constituted by those flags of the flag stream which indicate that the corresponding data transfer unit is to be retransmitted; and retransmitting the data.
