摘要 在本篇論文中我們利用TSR方法1-D(one dimension)[12]、2-D(two dimension)[13]來估測1-D與2-D分佈訊號(Distributed Sources)的中心入射角度(central angles)及其延伸寬度(extension width),對於相關分佈訊號(Coherently Distributed Sources)以及非相關分佈訊號(Incoherently Distributed Sources)的中心入射角度使用TSR(Transformed Subspace Rotation)來估測,而相關分佈訊號的延伸寬度是使用DSPE(Distributed Source Parameter Estimator) [1]的方法來估測,至於非相關分佈訊號的延伸寬度則是利用訊號的中央動差來求得[1]。相較於使用TLS-ESPRIT[1]的方法來解訊號的中心入射角度,TSR方法的計算量較少。兩種方法所估測出來的結果將會在實驗模擬結果中做比較。
Abstract Transformed Subspace Rotation (TSR) to estimate the parameters of 1-D and 2-D distributed sources is derived. The central angles are estimated by TSR .The extension widths of Coherent Sources are estimated by MUSIC algorithm. For Incoherently Distributed Sources, the extension widths are estimated using the central moments of the distribution. Comparison between TSR and TLS-ESPTIT, TSR can reduce the computational complexity with qualified performance in central angle estimation .
