Abstract

Based on negabinary encoding and weighting-shifting operation, a stacked optoelectronic outer-product complex multiplier module is proposed. By matrix partitioning and cyclic flow of the vector element, complex matrix-vector multiplication of arbitrary size can be performed using a limited number of such modules. The proposed methods are more efficient and have advantages in space-time bandwidth product.
