System, device and method for detecting and characterizing impairments in a communication network |
摘要 |
A device system and method of detecting impairments in a communication network, involving: receiving during a plurality of time intervals equalized training signals which are produced from training symbols that have been transmitted over the network and equalized; generating reference symbols corresponding to the training symbols and equalized training signals; indexing the equalized training signals by their time intervals and corresponding reference symbols; calculating errors due to impairments from the indexed, equalized training signals; and detecting impairments in the network from the calculated impairment errors.
