【Abstract】 This paper introduces the physical layer structure of IEEE 802.16, a standard for a new broad- band wireless access technology, and SUI(Stanford University Interim)channel models. Based on the standard, a comparative investigation on various channel estimation algorithms under a multi- path fading channel is presented and analyzed in this paper.更多还原
