在这封信中，导频的设计，旨在减轻MIMO OFDM系统中的小区间干扰。研究表明，如果假设干扰源和接收机之间存在理想信道，则可以设计出变异系数为零的导频，从而获得系统级的最佳性能。描述了这些导频的特性，并给出了数值计算和仿真结果来验证理论分析。
In this letter, the design of pilots aiming at mitigating the inter-cell interference in MIMO OFDM systems is addressed. It is shown that if an ideal channel between interferer and receiver is assumed, pilots resulting in a variation coefficient of zero, and therefore best performance on system level, can be designed. The properties of these pilots are described, and numerical calculations as well as simulation results are presented to verify the theoretical analysis.
