提出了一种新的宽带DOA估计方法:频域子空间正交性测试方法(TOFS:Test of orthogonality of frequency sub- space)。该方法通过同时测试频域信号共同带宽内各频段噪声子空间与阵列流形之间的正交性来进行DOA估计。与宽带相干信号子空间方法不同,TOFS方法不需要任何初始值的预估及聚焦操作。与宽带非相干信号子空间方法也不同,TOFS方法同时测试各频段噪声子空间与阵列流形之间的正交性。本文仿真了TOFS与IMUSIC、CSSM、TOPS的性能比较。仿真结果表明TOFS方法在中等信噪比以上时有较好的性能,且避免了TOPS方法中常出现的伪峰。 (Proposed a new broadband DOA estimation methods: subspace orthogonal frequency domain test methods (TOFS: Test of orthogonality of frequency sub-space). The method by simultaneously testing the frequency domain signal bandwidth of each band noise common sub-orthogonality between space and the array manifold to be DOA estimates. And broadband coherent signal subspace different methods, TOFS method does not require any initial estimate and focusing operation values. And broadband incoherent signal subspace methods are different, TOFS method for simultaneous testing of each band orthogonal noise subspace and the array manifold between. This paper compares the performance TOFS simulation and IMUSIC, CSSM, TOPS is. Simulation results show that the method TOFS better performance when more moderate SNR and spurious peaks TOPS method avoids the often occur.)

近年来随着移动互联网业务和物联网业务的兴起与 发展，用户对移动宽带业务需求越来越旺盛，对移动通信 网络的接入速率和质量要求也越来越高，原有基于码分多 址（CDMA）的3G及其增强技术未来将无法满足业务发展 需要，因此3GPP及3GPP2组织自2004年开始启动长期 演进（LTE）/空口演进（AIE，后改名为超移动宽带UMB）项 目，旨在通过引入一些关键技术，如正交频分复用（OFDM） 调制技术、多入多出（MIMO）技术、混合自动重传请求 （HARQ）、全IP扁平化架构及动态带宽分配等实现网络变 革，达到以下所述的网络性能，为移动宽带多媒体业务持 续发展提供技术保障。(Abstract:To meet the needs of mobile broadband services,LTE is being deployed and becoming ma－ tured,which includes key technologies such as OFDM,high-order modulation,HARQ,enhanced multi-antenna technologies,fast synchronization technologies,scalable control channel design,adap－ tive resource allocation,interference suppression technologies etc.Moreover,the discussion on LTE- Advanced has started,where technologies being considered includes aggregate multi-carrier,high－ er-order MIMO,smart relay,heterogeneous net－ work,multipoint collaboration as well as enhanced interference management.)
