Abstract
A method for transmitting pilots in a wireless communication system includes generating first two pilots for a first antenna. Second two pilots for a second antenna are generated by multiplying the first two pilots with two weight values respectively. The first two pilots are transmitted over two Orthogonal Frequency Division Multiplexing (OFDM) symbols via the first antenna. The second two pilots are transmitted over the two OFDM symbols via the second antenna, wherein each weight value is determined based on a value used to obtain a symbol index of a corresponding OFDM symbol of the two OFDM symbols within a slot. Symbol indexes for the two OFDM symbols are consecutive, and the two weight values are different with each other.
