Title:
【発明の名称】振幅変調された隣接チャネル干渉波信号を十分に除去するための装置および方法
Document Type and Number:
Japanese Patent JP2003510873
Kind Code:
A
Abstract:
An apparatus and method are provided that compensates for the problematic time-varying DC offset by effectively eliminating a near-channel amplited modulated interferer from a signal. The apparatus includes a first channel estimator for estimating a plurality of first channel filter taps H using a first signal model St, and a second channel estimator for estimating a plurality of second channel filter taps H using a second signal model St. The apparatus also includes a processor for selecting which of the first signal model St and the second signal model St is to be used or was used to substantially eliminate the near-channel amplitude modulated interferer from the received signal. The apparatus can be a mobile phone, base station, direct conversion receiver, or communications system (for example).
