摘要
针对超密集网络中导频复用将产生同一导频的复用干扰，严重影响信道估计的准确性，提出了一种超密集网络导频复用干扰避免策略。通过建立超密集网络子载波的干扰模型，推导子载波的干扰概率，并采用压缩感知理论建立超密集网络非均匀导频位置优化模型，据此提出了超密集网络导频复用干扰避免策略。仿真结果表明，与传统信道估计算法相比，所提策略增加了导频复用干扰避免策略的信道估计，能有效避免导频复用产生的干扰，保证信道估计的准确性。
Abstract
In the ultra dense network (UDN)
the pilot reuse scheme would produce significant interference
which will affect the accuracy of channel estimation.To solve this problem
an interference avoidance strategy for UDN with pilot reuse was proposed.An interference model of subcarriers for UDN was provided and the interference probability of subcarriers was derived.Then
based on the model
a pilot position selection model was proposed and an interference avoidance strategy for UDN with pilot reuse was provided.The simulation results show that compared with the traditional channel estimation algorithm
the channel estimation with proposed interference avoidance strategy can effectively avoid the interference and ensure the accuracy of channel estimation in UDN with pilot reuse.
