中文摘要 由於無線電波在室內環境中容易受到遮蔽物的影響,這些遮蔽物例如:牆壁、天花板以及傢俱等,使得無線電波經由多重反射、繞射等路徑而到達接收天線,此一現象稱之為多路徑效應(multi-path effect)。由於此效應造成的符際間干擾(InterSymbol Inference,ISI) ,使得通訊位元錯誤率(Bit Error Rate,BER)及失效率(outage probability)增加,亦即通話品質變差。在這篇論文裡,我們將探討室內的金屬傢俱在超寬頻(Ultra-Wide Band,UWB) 通訊上對位元錯誤率的影響。由於室內環境中不同位置的傳送器和接收器,所以我們利用射線彈跳追蹤法(Shooting and Bouncing Ray/image techniques, SBR/Image techniques)和快速反傅立葉轉換(Inverse Fast Fourier Transform,IFFT)技術計算其脈衝響應(impulse responses)。且透過這些多路徑通道的脈衝響應,使用二進制的脈波振幅調變(Binary Pulse Amplitude Modulation,BPAM)方法,進而計算超寬頻通訊系統的位元錯誤率。我們可以從數值結果得知金屬櫃其多路徑對於通訊位元錯誤率性能的影響。此外與木製櫃相比,金屬櫃的多路徑和環境失效率更為嚴重(大約相差18%)。最後,我們發現到目前這些模擬的情形不僅提供了比較的資訊,且更提供了性能減少這值得關注的訊息。
英文摘要 Radio wave is easily effected by obstacles in indoor environments. The obstacles are walls, ceilings, furniture in indoor environment. These obstacles will cause multiple reflection and diffraction of the radio waves and the phenomenon is called as multi-path effect. Due to this multi-path effect, the intersymbol inference (ISI) which increases the bit error rate and outage probability of the communication system occurred. As a result, the quality of communication becomes worse.
The bit error rate (BER) performance for ultra-wide band (UWB) indoor communication with 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 Fourier transform techniques. By using the impulse responses of these multipath 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 more serious (about 18%) than 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.
