Advances in Subspace-Based Techniques for Signal Processing and Communications

  1. Content type: Research Article

    This paper presents an adaptive method for maintaining paraunitary constraints on direct-form multichannel finite impulse response (FIR) filters. The technique is a spatiotemporal extension of a simple iterati...
