Angle Estimation Methods Toward Air-Ground Channels Dynamic Measurement
摘要
Abstract
Aiming at the low-latency demand for real-time angular parameter estimation in air-ground channel dynamic measurement,a low-latency and high-precision angular parameter estimation method for air-ground channel measurement system based on unmanned aerial vehicle(UAV)platform is proposed.The method can reduce the computational com-plexity of the traditional Multiple Signal Classification(MUSIC)algorithm in the process of covariance matrix computa-tion and eigenvalue decomposition by integrating the virtual array reduction technique and fast eigenvalue decomposition strategy.The field measurement data show that the method can significantly reduce the computation time and delay while maintaining the accuracy comparable to the classical algorithm,and is suitable for real-time angular parameter estimation in highly dynamic air-ground measurement scenarios.关键词
