Review of passive intermodulation suppression techniques in communication system
摘要
Abstract
The concept and negative effects of passive intermodulation(PIM)is described.After classifying the reason and the impact factors of PIM generation,the suppression and cancellation techniques of PIM in rescent years have been summarized.The paper not only generalizes the supperssion techniques from the perspective of manufacture,but also reviews and compares the optimization in digital domain and the cancellation in analog domain.The paper summarizes the methods to solve intermodulation distortion from the aspects of intermodulation generation modeling,low intermodulation design of passive device,intermodulation signal digital processing,intermodulation signal cancellation.At last the development trends of passive intermodulation suppression techniques are discussed.关键词
