Finding the location of an object is one of the important features of robotics applications, electronic warfare positioning, and the 3G/4G wireless communication systems. Many valuable location based services can be enabled by this new feature. Position estimation from Time Difference of Arrival (TDOA) measurements is one of the commonly used methods. This approach is based on intersections of hyperbolic curves defined by the time differences of arrival of signals received from different sources. The location is determined using standard complex computation methods that are usually implemented in software. In this paper, we propose new hardware-oriented algorithms that use only simple add and shift operations in the computation and therefore can be easily implemented in hardware.
