Method for controlling the signal gain of a multiband orthogonal frequency division multiplexing (MB-OFDM) baseband receiver

摘要

The invention provides a method for controlling the signal gain of a MultiBand Orthogonal Frequency Division Multiplexing (MB-OFDM) baseband receiver. The symbol boundary of a signal is first detected. Power of the signal is then measured according to the symbol boundary, so that a zero-padding section of the signal is not measured. A gain magnitude for amplifying the signal is then determined according to the power of the signal. The signal is then amplified according to the gain magnitude.
