Abstract

The sparse reconfigurable adaptive filter (SRAF) consists of an input delay bank, a photonic switch with reconfigurable connections and adaptive weights, and an output delay bank. This system architecture can be used to implement a sparse tapped delay line (TDL) with a large number of adaptive weights and a wide range of time delays. In this paper, we investigate some delay properties of the SRAF and consider an adaptive algorithm based on a cross-correlation function of the pre-whitened input and a desired response signal. Computer simulations are presented to illustrate the behavior of the SRAF for a system identification application
