The paper is devoted to the development of a WOLA-algorithm (weighted overlap add algorithm) for processing vector (multichannel) signals. The algorithm is considered as a generalization of one-dimensional WOLA with certain modifications. WOLA is expounded as an algorithm for real-time signal processing and the main advantages of WOLA are provided. We also discuss software-hardware implementation of WOLA using CPU (Central Processing Unit) and CUDA (Compute Unified Device Architecture). Finally we demonstrate the possibility of reducing hardware costs for multichannel signal processing using FPGA (field programmable gate arrays) and distributed arithmetic.
