Abstract The agorithm of RLS to suppress unknown narrowband interference is proposed by analyzing the received signals’s statistical character when the narrowband interference is unknown in DS-SS systems. Compared with Blind Recursive Least-Square, it doesn’t need limiting condition and reduces the complication.What is more, it makes up the shortcoming that the agorithm of LS cannot process the real-time signal, and is implemented with fast algorithms. The simulation results show that the performance to suppress narrowband inteference for DS-SS systems by the agorithm is better than the one of adaptive linear filter, and the convergence is not cared. It’s easier to be applied.
