Abstract :
Channel estimation in coherent OFDM by inserting pilot-symbols into two-dimensional time-frequency lattice is a promising candidate for improving channel transmission capacity in future wireless communication systems. This paper proposes a new Cartesian mathematical concept of the hexagonal pilot pattern, hexagonal pilot with virtual and rectangular pilot pattern. The main focus of this work is to compare between the two pilots and by virtue of simulation conclusion which of the two pilots yields a better performance.
