In an 802.11 wireless environment, signals that use Or-thogonal Frequency Division Multiplexing (OFDM) and OFDM with Cyclic Prefix Code (OFDM-CPC) present interference to other wireless users. This work thoroughly analyzes the interference these signals cause and contrasts the results to that of narrow band interferers. Smart an-tennas with tapped-delay-lines are used to mitigate the interference effect from these signals. The optimal values for the delay lines parameters (number of taps and amount of delay provided by each delay unit) to restore the per-formance at minimum cost are found.
Mr. Ayham Z. Al-Banna is a Ph.D. candidate in the Electrical and Computer Engineering department at the Illinois Institute of Technology (IIT). He studies the impact of wireless interference on communication networks. Mr. Al-Banna graduated from the University of Jordan in 2001 with a Bachelor’s degree in electrical engineering. He joined IIT in the Fall of 2001 and received his Master of Science degree in electrical engineering in May 2003. His master’s research dealt with optimal cellular system layout design.
