Abstract

Time resolution of multipath delay profiles measured by using the autocorrelation of a 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. The effectiveness of this method is demonstrated by an indoor wireless propagation experiment using circularly polarized wave at 900 MHz, and the number of multipath is given unambiguously
