軟體定義無線電(Software Define Radio)理論的出現,被視為解決新一代通訊,支援多重標準、多模式操作及功能可重組(Reconfigurable)需求的一項重要技術,這項技術可以在一個可程式的無線電硬體上,利用可重組的軟體技術來達到支援多個通訊頻段、調變方式及不同頻寬需求的操作,增加了硬體使用的彈性。
本論文利用數位信號處理晶片易於程式化的優點,研究以TI C6x晶片的發展工具做為無線電的核心運算平台,搭配自行設計的連接子卡,將數位類比轉換器及類比數位轉換器整合成一個可重組的傳收機系統實體。在軟體演算法方面,這裡使用C語言發展了QPSK及16QAM兩種調變方式來測試傳收機的功能,經由演算法的計算錯綜性分析及實驗驗證結果,本傳收機傳輸符碼率可以輕易達到750K symbols/sec的效能。
The philosophy of Software Defined Radio being a key technology for next generation wireless communications, needed to support multi-standard, multi-mode and function re-configurable radio designs. This technology refers to the class of reconfigurable radios in which hardware is reprogrammed to support different frequencies, frequency bandwidths as well as different modulation schemes resulting in significant increases in hardware flexibility.
This thesis exploits easy to use DSP programming software to reconfigure a transceiver built around the TI C6x DSK and ADC/DAC connected through an experimental daughter card specifically designed for this purpose.
Two different modulation schemes (QPSK and 16QAM) are implemented using C algorithm to demonstrate the computational complexity of the proposed system. Supporting experiments presented in this thesis shows attainable symbol rate is 750K symbols/sec.
