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.
