Abstract

Abstract

The one delay tap cancellation system is weakly to suppress the co-site interference between the Very High Frequency (VHF) radios in multipath channel. To overcome this obstacle, a Radio Frequency (RF) interference cancellation scheme based on the multi-tap delay and orthogonal combination is presented, as well as a new solving attenuation coefficients method. Considering the fixed delay scale and the number of taps, this method accurately estimates the reference signal autocorrelation matrix and the cross-correlation vector between reference signals and received signal on the basis of instantaneous and iterative weighted averaging. The attenuation coefficients are achieved by solving Wiener-Hopf equation via the estimated autocorrelation matrix and cross-correlation vector. Compared with the existing approaches, this method does not need to adjust and control the amplitudes as well as the phases of reference signals simultaneously, and it improves the accuracy of estimating cross-correlation vector and autocorrelation matrix. In addition, the closed-form expression of self-interference cancellation ratio is derived through theoretically analyzing the attenuation coefficients solution. The analysis and simulation results show that the proposed method could obtain self-interference cancellation ratio of more than 90 dB, which is about 9 dB higher than the existing method. This study is significant for eliminating RF self-interference in multipath channel.
