Abstract The advantages of subband signal processing adaptive array (SBAA) are the ability to perform parallel signal processing in each subband division and the substantial reduction in the total computational load. However, the price is not preventing a drop in performance, for example, the incorporation of delayed waves, and a countermeasure must be found. Therefore, in this paper, we propose introducing a scheme that inserts a guard interval (cyclic prefix), which is commonly adopted in Orthogonal Frequency Division Multiplexing (OFDM), into ordinary data transmission, and extracts the best possible performance of SBAA. We also evaluate the performance by a computer simulation. © 2002 Wiley Periodicals, Inc.
