A convex projections method for improved narrow-band interference rejection in direct-sequence spread-spectrum systems Academic Article uri icon

abstract

  • A method is presented for enhancing the narrowband interference rejection capability of direct-sequence spread-spectrum systems employing an adaptive notch filter. The method, based on projection onto convex sets, restores that part of the spread-spectrum signal distorted by the filter. Simulation results are presented which show the output bit-error rate (BER) improvement gained by using the signal restoration scheme. © 1997 IEEE.
