Abstract(in English) | ODFM symbol has Guard-Interval(GI). If time of delay waves is not over GI, symbol interference does not happen. However, delay waves, which delay time is under GI, generate notches on frequency domain, and CNR of some sub-carriers languish. In this report, we give multi-beam antenna to BS of in-door wireless communication system, and discuss about radiation patterns that are more effective for the system. Maximum delay times in in-door, coverage of direct wave and delay profiles are calculated by ray-trace method. And we find DUR from a facilitated model that is integrating multi-pass from delay profile. As a result of simulation, it transpires that DUR lessen and BER improves by adjusting 3dB band width and tilt angle. |
