隨著通訊應用的普及與網路時代的來臨,網路對人們來說,已經是生活的一部分。近年來,由於無線網路的發達,擺脫了以往有線網路佈線的限制,無論何時何地皆可自由地上網,進而使得人們對於無線通訊的需求日益增長。無線區域網路 ( Wireless LAN ) 發展至今,隨著不同應用的需求,不同的規範與標準也應蘊而生,對今日的電腦及通訊產業而言,無線應用儼然已成為一個重要的觀念及技術。
在現有的數位通訊系統中,正交分頻多工系統 (OFDM)是常被使用之調變技術。正交分頻多工系統與傳統單載波調變系統最大的差異之處,乃是它採用了多載波調變的技術,此方法目前已規範於802.11x、DAB、DVB等應用標準中,從硬體實現的觀點而言,可透過快速傅立葉及反傅立葉轉換 (FFT/IFFT) 的運算來達到調變與反調變之目的。但是不同應用標準意謂著有不同之FFT/IFFT規格需求,同時,在同一數位通訊系統亦可能包含不同的操作模式,因此,如何設計一個能夠滿足不同的通訊系統標準及操作模式所需的調變解調電路的系統,將是一項挑戰;而本論文便是針對此一課題,提出如何製作一有效率之 FFT/IFFT 編譯器來符合快速電路設計之目的,進而作為後續更深入研究之基礎。
With the emergence of internet services and pervasion of communication applications, internet and wireless communication have become a part of our life. Wireless network can reach where the traditional network cannot do. This makes the applications of wireless network more widespread. To date, different wireless LAN standards have emerged from different applications and each standard has its own uniqueness and application ranges.
Of the existing digital communication systems, the Orthogonal Frequency Division Multiplexing (OFDM) technique has been widely used in performing signal modulation. Compared with the traditional single-carrier frequency modulation technique, OFDM adopts multi-carrier modulation which has been adopted in many practical wireless systems such as 802.11x, DAB and DVB, etc. Regarding the hardware implementation, the OFDM can be fulfilled by employing the (inverse) fast Fourier transform (FFT/IFFT). In fact, different standards or operation modes imply different requirements or specifications for the associated FFT/IFFT; therefore, different design methodology should be applied. It would be a challenge if a unified FFT/IFFT architecture is to be designed. In this thesis, we investigate how to develop an efficient FFT/IFFT compiler for different applications. Based on our development, not only a dedicated FFT/IFFT module can be easily prototyped for fast system verification, but also the resulting compiler can be used as a basis for more advanced research in the future.
