Abstract

Abstract:

The multi-tap interference cancellation structure can be used to suppress the wideband noise interference generated by high-power transmitters. The selection of the number of taps and the tap delay interval directly affects the interference suppression effect. However, the existing references lack selection methods and the analysis of the impact of multi-tap interference cancellation system performance. To solve this problem, the theoretical model of the multi-tap digital-analog hybrid cancellation system is established, the optimal value of the tap weight is solved, and the analytical relationship between the tap number and delay interval and the interference cancellation ratio (ICR) and convergence speed is obtained for the first time. To reduce the complexity of weight estimation, the exponential iterative weighting method is proposed, which effectively improves the weight estimation accuracy and the ICR. For the selection strategy of the number of taps and the tap delay interval, the selection criterion with the highest ICR and the fastest convergence speed is proposed, which greatly reduces the cost-effectiveness ratio and can provide reference for the selection of the number of taps and tap delay interval in the multi-tap cancellation structure. The results show that for the signal with a bandwidth of 30 MHz, the ICR of the optimized system is not less than 33 dB, which effectively solves the problem of wideband interference.

Key words: multi-tap, number of taps, tap delay interval, interference cancellation ratio (ICR), convergence speed
