A DSP-based fuzzy system for real-time interference cancellation in DS-SS systems

This work demonstrates that high-end classical programmable digital signal processors (DSPs) can implement fuzzy systems for real-time communication processing. A systematic procedure to program the DSP is also described. A Fuzzy Narrowband Interference Canceller (NBI) has been designed and its performance compared when its membership functions are triangular or gaussian. Furthermore a comparative study with other cancellers has been carried out.
