A Simple Superresolution Method of Multipath Delay Profiles

摘要

Time resolution f multipath delay profiles measured by using autocorrelation of pseudonoise(PN) code sequence is generally limited by the chip rate of the PN code sequence. In this paper, we proposed a simple method to improve the time resolution of delay profiles measured by the PN correlation method. Effectiveness of this method is demonstrated by an indoor wireless propagation experiment using circularly polarized wave at 900MHz, and the number of multipath is given umambiguously.
