Abstract
In this paper, the Balise Uplink signal noise feature and noise process method are researched. The model of the transmission channel for Uplink signal is established, and the AR power spectrum model is used to extract the noise feature. Then an adaptive noise cancellation is proposed based on the noise feature extraction. This method improves the SNR of the Uplink signal, so that Balise Uplink signal transmission is more reliable.
