Abstract

Methods and communication terminals for estimating noise in a multicarrier communication system where multicarrier symbols are received that include pilot signals channel properties are estimated based on the received multicarrier symbols wherein the channel properties include channel properties of a subcarrier carrying one of the pilot signals and the channel properties of the subcarrier carrying one of the pilot signals are mixed with the corresponding pilot signal to calculate a noise power for the corresponding subcarrier.
