基于信号正交性的TIS系统定时失配盲校正方法
Blind Timing Mismatch Correction Method for TIS System Based on Signal Orthogonality
摘要
Abstract
In order to solve the problem of timing mismatch between channels in time-interleaved sampling(TIS)systems,a signal-orthogonality-based timing calibration(SOTiC)is proposed.Based on the signal orthogonality and adaptive iterative algorithm,the estimation and correction of time mismatch parameters in dual-channel TIS system are completed.The multichannel extension structure is derived,and the two-channel correction structure is extended to the M-channel TIS system through odd-even channel recombination.The theoretical and experimental results show that SOTiC has the advantages of fast convergence,small steady-state error,low computational complexity and good scalability,and can be widely used in online correction of timing error in high speed/ultra high speed sampling systems.关键词
