Abstract
A space diversity scheme for an orthogonal frequency division multiplexing (OFDM) system designed for in-house application such as wireless local area network (WLAN) or wireless home network is proposed. In the proposed scheme, the antenna is selected in accordance with the dip width of the frequency spectrum of the transmission channel. The diversity effect is evaluated by simulation in a typical multipath environment in a house. The delay spread of 30 ns and the maximum Doppler frequency of 0.5 Hz are assumed. In this paper, the PER is considerably improved by more than one order (1/10) by using the proposed scheme when the carrier to noise power ratio (CNR) is high.
