Pathlet: A new wavelet for resolving the constituent components in a multipath channel

摘要

This paper presents the construction of a novel set of finite filter coefficients with symmetric impulse response, resulting in the development of a wavelet family which is named "Pathlet", for use in multipath channel parameter estimation. It makes use of digital filter design techniques. The generated Pathlet family is subsequently used as analyzing wavelets in the resolution of constituent multipath components in simulated multipath delay profiles. In particular, it is shown that the new wavelet family can be successfully used to resolve the different paths in a multipath delay profile
