Abstract :
Transmission of a multi-carrier (MC) signal through the multipath fading indoor channel is explained and its capability to combat the frequency selectivity of the channel as well as to provide spectral efficiency and also its effective implementation with discrete Fourier techniques is described. Performance of orthogonal frequency division multiplexing (OFDM) with BPSK modulation is evaluated over a large empirical data base of indoor radio propagation channels. These indoor channels have lognormal amplitude fading and modified Poisson distribution of the arrival time of multipath components. The performance is evaluated in terms of the average probability of bit error as a function of signal-to-noise ratio. The influence of changing the number of tones as well as the guard interval on the average bit error rate is investigated. Results can be used in design and assessment of high speed indoor wireless communication systems
