A systolic architecture is proposed for the real-time implementation of broadband 2-D IIR beam filters having applications in ultra-wideband (UWB) radio frequency (RF) antenna arrays. Real-time throughputs of one-frame-per-clock-cycle are achieved. A finite-difference time-domain computational electromagnetic model of a typical indoor propagation environment is used to illustrate that the method significantly reduces the bit error rate of the simulated communication system in the presence of multi-user interference, thereby demonstrating the potential application of the architecture in RF communications.
