LTE中一种新的干扰与噪声功率估计方法
A New Method of Interference and Noise Power Estimation in LTE
摘要
Abstract
A method is proposed to estimate the interference and noise power using synchronization signal for Long Term Evolution (LTE)/Long Term Evolution-Advanced(LTE-A) systems. In this method, the channel coefficient of current subcarrier is estimated, and the estimated received signal of adjacent carrier is calculated based on the hypothesis that the channel coefficients of two adjacent carriers are nearly equal. Correlation of the difference value of the real received and the estimated value is performed with further expectation operations for estimation of interference and noise power. Simulation results show that proposed method performs better than conventional Cyclic Prefix(CP) algorithm in rich multipath fading scenarios, and the method can estimate interference and noise power well.关键词
