METHOD AND APPARATUS FOR DETECTION AND CANCELLATION OF SINGLE-TONE OR MULTI-TONE INTERFERENCE IN COMMUNICATION SYSTEMS
Abstract:
A method and system for canceling an interference signal are provided. In the method, a received signal is transformed from a time domain to a frequency domain at relative low precision to obtain an estimated frequency and an estimated amplitude of the interference signal. A reference signal is generated using the estimated frequency and the estimated amplitude. An error signal is generated using the received signal and the reference signal based on minimum correlation criteria. The reference signal is adjusted using the error signal based on an adaptive algorithm. The reference signal is subtracted from the received signal to obtain the useful signal.
Abstract(Chinese):

提供一种用于消除干扰信号的方法和系统。 在该方法中，接收信号以相对低的精度从时域变换到频域，以获得干扰信号的估计频率和估计振幅。 使用估计频率和估计振幅来产生参考信号。 基于最小相关准则，使用接收信号和参考信号产生误差信号。 使用基于自适应算法的误差信号来调整参考信号。 从接收信号中减去参考信号，以获得有用的信号。
