| description | This paper discusses the transmission of the
Orthogonal Frequency Division Multiplexing (OFDM)
signal through the multipath fading indoor channel and
its capability to combat the Intersymbol interference
(ISI) as well as its eflective implementation with the
discrete Fourier transform is, described.. The channel
model used was based on Saleh-Valeuzqeia model with
loghormd fading distribution ,of 'gain 'amplitudes.
Simnlation.modules were developed and the eflect of the
multipath 'on the, OFDM system. performance with
BPSK, QPSK, l6PSK, 64PSK 16QAM, 64QAM, and
l28QAM modulations was evaluated in terms of the bit
error rate @ER) as a function of the energy per hit-tonoise
ratio (EBNR). The influence of the number of
carriers as well as the guard interval duration on the
performance.was.'also investigated. Simulations showed
that the EBNR required to achieve a certain BER is
significantly increased by 8-10 dB for dense multipath
fading channels over that required in AWGN channels.
These performance measures are useful for the design
and assessment of high speed ' indoor wireless
communication systems.
