摘要
Abstract
For the increasingly complicated applications of communication system and higher electromagnet-ic compatibility requirements for equipment under complex electromagnetic environment, an interference cancellation technology based on the mixed analog and digital circuit is proposed. After the principle anal-ysis,an elementary prototype for interference cancellation is developed and tested. The corresponding ex-perimental results indicate that point frequency and noise interference can be suppressed with a conver-gence time less than 100 ms and a cancellation ratio greater than 43 dB. The cancellation technology is suitable for narrowband communications and also worth spreading to other areas. It has been applied in practical engineering.关键词
