ABSTRACT


The bit error rate (BER) performance for ultra-wide band (UWB) indoor communication with the impact of metallic furniture is investigated. The impulse responses of different indoor environments for any transmitter and receiver location are computed by shooting and bouncing ray/image and inverse fast Fourier transform (IFFT) techniques. By using the impulse responses of these multi-path channels, the BER performance for binary pulse amplitude modulation (BPAM) impulse radio UWB communication system are calculated. Numerical results have shown that the multi-path effect by the metallic cabinets is an important factor for BER performance. Also the outage probability for the UWB multi-path environment with metallic cabinets is larger than that with wooden cabinets. Finally, it is worth noting that in these cases the present work provides not only comparative information but also quantitative information on the performance reduction.


Keywords: UWB, BER, Outage Probability, RMS Delay Spread
