摘要
The weighted minimized least square (WMLS) method by Chan based on TDOA source localization can achieve the Cramer-Rao lower bound (CRLB) under far field, noise environment. The paper provides a modified algorithm to remove the bias of WMLS. Bias-Subtract method is proposed to removes the expected bias from the solution of WMLS. The new method has much less bias than WMLS and MSE performance can achieve CRLB.
