Abstract
The present invention relates to a method and apparatus for TDOA wireless positioning, has an effect of reducing positioning errors by reducing TDOA errors using destructive interference of multiple anchor nodes by dividing four or more anchor nodes into sets of three or more anchor nodes and by estimating a position of a tag node using TDOA of each set, and has an advantage of reducing the size and weight of the tag node since separate hardware is not required.
