Abstract :
A study of interference caused by adjacent IEEE 802.11 Barker-code spread and complementary code keying spread wireless fidelity signals used in wireless local area networks is presented. The interference resulted from these signals is thoroughly analyzed and compared to that caused by bandlimited flat spectral interferers as well as narrow band interferers. Adaptive antennas employing tapped-delay-lines are used to mitigate the interference effect from these signals. The optimal values for the delay-line parameters to restore the performance at minimum cost are found
