A programmable MVDR beamformer by switched-capacitor circuits

A real-time adaptive antenna array based on a neural network approach is presented. Since an array operating in a nonstationary environment requires a programmable synaptic weight matrix for the neural network, the switched-capacitor (SC) circuits with the capability of programmability are employed to implement the neural-based adaptive array. A simulation tool called SWITCAP is used to verify the validity and performance of the proposed implementation.<<ETX>>
