Abstract-The performance of OFDM systems over a multipath channel can strongly degrade due to the propagation delay spread. The distortion of the received signal over the FFT window, is referred to as multipath noise. This work aims to determine analytically the performance loss due to multipath noise as a function of OFDM and channel parameters for narrowband OFDM systems. First, it is investigated whether it is possible to describe the multipath noise, varying over different OFDM packets due to the temporal variation of the channel, by an effective noise factor F delay , from which the loss factor is directly determined. Secondly, the theory of room electromagnetics is applied to develop a closed-form expression for F delay as a function of the OFDM and reverberation parameters. This analytical method is validated with excellent agreement. Finally, the loss factor is determined for IEEE 802.11 based on channel measurements in 2 large conference rooms, providing values up to 19 dB for an 800 ns cyclic prefix length.

“…Note that RF transceiver chip includes a 6-bit digital-to-analog converter (DAC) and 4-bit I/Q analog-to-digital converters (ADCs). The receiver adopts zero-IF architecture to have low power consumption, low cost and small size (M. Valla et al (2005), Ilku-Nam et al (2003), Kwang-Jin Koh et al (2004), M. Zargari et al (2004), S. F. R. Chang et al (2005), W. Hioe et al (2004). The RF front-end circuits of receiver are shown in Fig.3.…”
