Abstract
One or more systems and methods are provided for performing estimation of position and orientation (localization) of an object using wireless signals. This localization can be done either with sensors already built into the device or via a module installed onto the object. The method further includes obtaining a channel state information (610) from a wireless receiver (1204) and obtaining an angular velocity (608) from an inertial measurement unit. Further, the data between the inertial sensor (602) and the wireless sensor (606) is fused by maximum likelihood, expectation maximization and other such variants to perform Angles of Arrival (AoAs) and Times of Flight (ToFs) estimation on the wireless receiver. The orientation can be estimated by combining the estimates from gyroscope (1104) with these estimated AoAs and with accelerometer (1106) and magnetic sensor (604) inputs, making the orientation estimation driftless. Once the estimations are calculated, the values can be used to perform displacement calculations and these calculated displacements can be used for tracking of the wireless receiver.
