Exploiting time diversity to improve block spread OFDM

This paper presents a new method to improve on block spread OFDM by exploiting time diversity to ensure that the blocks are independent and uncorrelated. Simulation results have shown significant improvement over conventional OFDM and Block Spread OFDM. Disciplines Physical Sciences and Mathematics Publication Details Raad, I. S. & Huang, X. (2006).
