概要	Oblique projectors can be useful for interference suppression in direct-sequence code-division multiple-access (DS/CDMA) communication systems. In this paper, we propose a recursive oblique projector that exploits the Gram–Schmidt process. When increasing or decreasing the number of accessed users in the system, the oblique projector can be updated recursively by using the proposed method. Simulation results demonstrate that the proposed method is more computationally efficient than the conventional construction process of oblique projectors without the degradation of bit-error-rate (BER) performance in the DS/CDMA system.
