摘要：

Due to the effect of time-varying passive intermodulation on the performance of communication receivers, the passive intermodulation interference was modeled based on power series. Three adaptive two-dimensional time delay estimation algorithms were proposed according to the practical engineering application. The time delay estimation implementation methods of binary search, fast binary search and parallel search were described, simulated and compared. The simulation results indicate that all the three search methods can work after different iterative learnings. Among them, the two-dimensional time delay estimation algorithm based on fast binary search is more suitable for hardware implementation with less resource and faster tracing speed. The experimental results show that, the prototype with the two-dimensional time delay estimation algorithm based on fast binary search can estimate the two-dimensional time delays accurately and achieve a good performance. © 2019, Editorial Department of Transaction of Beijing Institute of Technology.
