Abstract :
The performance of direct-sequence spread spectrum systems in the present of narrowband interference rejection is studied employing decision feedback filters. Closed-form analytical expressions for the system´s performance are derived. Both analysis results and numerical simulation results show that DF filters outperform linear prediction filters by comparison.
