Abstract

Abstract: Estimation of channel frequency response through insertion pilot is an important content of the channel estimation technique.At present,there are three kinds of pilot insertion plans:messive,honeycomb and astooid distribution eaching having its flaw respectively,which limits the application environment.This article proposes one kind newly based on the diagonal pilot structure algorithm.The new algorithm has high spectrum efficiency and good is algorithm performance;moreover,it reduces the arithmetic complexity.

Key words: channel estimate, diagonal pilot structure, interpolation
