Abstract

A method of estimating channel state information (CSI) of a Multiple Input Multiple Output (MIMO) channel includes transmitting pilot symbols from a plurality of transmission antennas, wherein a number of pilot symbols are transmitted using chirped signals based on the Fresnel transform for generating Orthogonal chirp-division multiplexing (OCDM) signals, the number of pilot symbols overlap in time-domain, a single symbol interval is utilized to estimate a transfer matrix of the MIMO channel, and no silent pilot symbols are transmitted.
