N2 - As demand grows for digital wireless communication systems, the accurate prediction of average and instantaneous bit error rates (BER) for different modulation schemes will become increasingly important in system design. BER predictions will not only provide an understanding of the perfor mance of each modulation method in the operating environment, but will also reveal the limits of data rate and channel capacity. This research uses a statistical multipath channel simulator, Simulation of Indoor Radio Channel Impulse Response Models (SIRCIM) [1], to generate realistic channel responses over local areas for both wide-band and narrow-band (CW) radio transmissions inside open plan buildings, and predicts BER for FSK, BPSK, and π/4 DQPSK modulation techniques in flat fading channels through computer simulation. The small-scale channel model, the communication system models used in the analysis, and the methods used to predict BER, are de scribed in this paper. In fact, one of the goals of this work is to present a straightforward simulation methodology that can be readily used. The channel simulator and the systems models have been thoroughly tested, and results from average and instantaneous BER simulations are shown. The BER performances of various modulation techniques in indoor flat fading channels are presented, and it is found that BPSK offers be tween a 2.8 and 3.0 dB improvement over π/4 DQPSK, although the latter offers a 3 dB increase in capacity for a given spectrum allocation.
