Abstract
In this paper, we address the problem of the design of pilots aiming at mitigating the inter-cell interference in OFDM systems. Based on the conventional pilot design used in the intra-cell, we design the pilots which can make the power of inter-cell interference distribute in all paths of the channel uniformly, and result in a variation coefficient of zero, then the better performance on system level will be derived. The properties of these pilots are described, and the simulation results are presented.
