摘要

•The inter-correlation of acceleration signals is exploited for data loss recovery.•A new projection matrix named Permuted Random Demodulator (PRD) is proposed.•The PRD matrix makes the data loss recovery scheme robust to continuous data loss.•Modal parameters are successfully identified using the reconstructed data.
