Correction: Distributed beamforming designs to improve physical layer security in wireless relay networks Mujun Qian1, Chen Liu1* and Youhua Fu1,2 Correction In our paper Distributed beamforming designs to improve physical layer security in wireless relay networks [1], several equations should be corrected as indicated below. In section 2.1 ‘Amplify-and-forward’, the equation included in the paragraph above Equation (2) incorrectly read as follows: ti = wiρiri This equation should read correctly as follows: ti = wi*ρiri In section 2.2 ‘Decode-and-forward’, the equation included in the paragraph above Equation (4) incorrectly read as follows: ti = wis This equation should read correctly as follows: ti = wi*s In Equations (2–5), (7–8) and (25–26), wT is incorrectly included. In all of these equations wT should be replaced with wH.
