METHOD AND DEVICE FOR DETERMINING THE LINK QUALITY IN AN OFDM NETWORK

摘要

A device for determining link quality of an OFDM communication link having a pilot sub-carrier, the device comprising means for determining a signal power associated with the communication link; and means for comparing a characteristic of a pilot signal received on the pilot sub-carder with a channel coefficient determined from a training symbol received over the communication link to allow determination of a distortion measurement, wherein the ratio of the signal power to the distortion measurement provides a link quality determination for the communication link.
