A novel unitary beamspace recursive least squares (UB-RLS) algorithm for fast adaptive beamforming is proposed in this paper. Firstly, a kind of random unitary transformation matrix is designed. Secondly, with these matrices, the feed signals are tra

In this paper, we introduce a new ultra-thin microwave absorber made by a proper array of split-ring resonators (SRRs). And we propose that while using vertical split-rings cells to replace the single split-rings cells, the polarization dependence ca

Adaptive beamforming methods degrade in the presence of both signal mismatch and interference nonstationarity. This paper presents a more robust method to adaptive beamforming that provides joint robustness against signal mismatch and interference no

In this paper, frequency selective surface with random distributed resistance patches (RRDFSS) has been proposed and the effects of occupancy factor, distribution and surface resistance have been studied numerically with HFSS. The results show that o

A new fast direction of arrival (DOA) estimation algorithm based on direct data domain least square (D3LS) approach is presented. The matrix equation, which is formed according to the idea of D3LS, is solved via the conjugate gradient (CG) method to

A phase-only direct data domain least square (D3LS) algorithm based on the nonlinear conjugate gradient (CG) method is presented. The cost function is obtained via the normal D3LS algorithm as a first step, and then optimized with the nonlinear CG me

Recently, a direct data domain least square (D3LS) approach has been developed so quickly for array signal processing in mobile communication and radar application. With D3LS approach, only a single data snapshot is required, instead of multiple snap
