Abstract

Based on the mixed negative binary number system, we propose an inner-product algorithm for digital complex-valued matrix–vector multiplication. The features are no carries, no signs, no indications for decimal points, and simple preprocessing and postprocessing. Correspondingly, an optical architecture of incoherent optical correlation with spatial digital coding of data is suggested. Negative binary complex matrix–vector multiplication can be realized optically in parallel with a high accuracy. The experimental result is also given.
