Abstract:
An estimating method for maximum channel delay and cyclic prefix (CP) averaging method in orthogonal frequency division multiplexing (OFDM) receiver are described. Specifically, the estimating method performs the estimation of the maximum channel delay by adding the CP and the main OFDM signal for increasing the signal-to-noise ratio (SNR) and for reducing the inter-carrier interference (ICI). The CP averaging method is used to acquire a portion of the CP by using the maximum channel delay so as to increase the performance of the OFDM receiver.
