This paper proposes a method that solves the problem of geometric calibration of microphone arrays. We consider a distributed system, in which each array is controlled by separate acquisition devices that do not share a common synchronization clock. Given a set of probing sources, e.g. loudspeakers, each array computes an estimate of the source locations using a conventional TDOA-based algorithm....
Precise estimation of the position and transmission power of the primary user is of great importance in cognitive radio (CR) networks. These information can help the secondary users to exploit the spatial resources better and reduce the interference with primary users. In order to find position of the primary users, we propose a new cognitive situated received signal strength (RSS) algorithm. Existing...
A novel efficient trilateration algorithm is presented to estimate the position of a target object, such as a mobile robot, in a 2D or 3D space. The proposed algorithm is derived from a nonlinear least-squares formulation, and provides an optimal position estimate from a number (greater than or equal to the dimension of the environment) of reference points and corresponding distance measurements....
