Patent ID: 7664190

Claim:
A multi-carrier receiver with dynamic power adjustment, comprising: a demodulator receiving a multi-carrier signal, wherein the multi-carrier signal comprises a plurality of sub-carriers; a channel estimator estimating channel characteristics of each sub-carrier from the demodulated multi-carrier signal; multiprotocol capsulation forward error correction estimating channel characteristics of each sub-carrier from the demodulated multi-carrier signal; a system performance detector detecting a system performance; an ICI canceller subtracting the estimated ICI included in the received multi-carrier signal from the demodulated multi-carrier signal; a determination circuit turning on the ICI canceller when the ICI strength exceeds an ICI threshold and the system performance is less than a system performance threshold; and an equalizing the demodulated multi-carrier signal based on the estimated channel characteristics, wherein the equalized multi-carrier signal is supplied to the system performance detector for updating the system performance.
