Design of a wideband adaptive filter incorporating a surface-acoustic-wave monolithic zinc-oxide-on-silicon storage correlator is reported. Its operation is demonstrated with experimental measurements of c.w. interference suppression in a simulated spread-spectrum system. These processors, which are capable of adaptive filtering over 1–20 MHz signal bandwidths in real time, offer significant advantages in terms of complexity and power consumption over equivalent digital systems.
