Optimization Algorithms

The optimization algorithm are used to estimate the location of a node using the measurements. The measurements can be based on time (\(\in \{\) ToA, TDoA, RTT \(\}\)), angle (\(\in \{\) AoA, AoD \(\}\)) or received power (RSRP). Different optimization framework can be used for estimating the location. 5G toolkit provides least square, Gradient descent and Newton Raphson based algorithms which are discussed below.
