METHOD AND APPARATUS FOR ESTIMATING A NOISE POWER FOR OFDM
摘要
<p>A method and apparatus for estimating noise for orthogonal frequency division multiplexing (OFDM) are disclosed. A time domain difference signal and a frequency domain difference signal between two consecutive received pilot symbols are calculated. A time domain noise power is calculated from the time domain difference signal and a frequency domain noise power is calculated from the frequency domain difference signal. The time domain noise power and the frequency domain noise power are combined to estimate the noise power.</p>
