Method and apparatus for implementing clear channel assessment function in multi-band OFDM system
A clear channel assessment CCA method implemented in a multi-band orthogonal frequency division multiplexing (OFDM) system, the method including: estimating an energy of a received signal in each window at predetermined intervals of two moving-average windows; detecting a peak value according to a difference of energies estimated in relation to the two moving-average windows, and accumulating a number of detected peak values; and reporting a channel status to a medium access control (MAC) according to the number of the accumulated peak values.
