Abstract
A method of transmitting pilot signals by a transmitter in a multiple-input multiple-output (MIMO) antenna system using an orthogonal frequency division multiplexing (OFDM) scheme includes allocating pilot subcarrier locations within a resource block including OFDM symbols in a time domain and subcarriers in a frequency domain based on variables of '18k', '9mi' and ‘floor (ns/2)’, wherein ‘k’ indicates a subchannel index, ‘ns’ indicates a symbol index, ‘mi’ corresponds to ‘(ns+i)mod 2’, ‘i’ indicates an antenna index, wherein ‘floor (n)’ denotes a greatest integer that is not greater than ‘n’; and transmitting the pilot signals to a receiver based on the allocated pilot subcarrier locations.
