Closed‐form solution for scaling a wireless acoustic sensor network
IET Wireless Sensor Systems, 2023 Abstract A closed‐form solution for localising and synchronising an acoustic sensor node with respect to a Wireless Acoustic Sensor Network (WASN) is presented. The aim is to allow efficient scaling of a WASN by individually calibrating newly joined sensor nodes instead of recalibrating the entire array. A key contribution is that the
