dc.description.abstract | 隨著行動通訊的快速發展,基地台所需要進行的基頻運算也越來越多,未來有可能將大部分的基頻運算以軟體方式集中於基地台的計算平台進行基頻處理、協作運算等,而由於高流量以及部分基頻信號處理所帶來的高平行性,非常適合平行處理,於是我們使用開放式計算語言(Open Computing Language OpenCL),其提供一個適用於各種不同裝置的平行化計算平台,透過平行運算來去提升運算效能,在本論文中,我們透過OpenCL實作下行非正交多工存取基頻接收機。
在本論文中,以NI射頻模組化儀器為傳送端,NI-USRP 2932為接收端,射頻模組化儀器經過空氣傳送訊號,在Ubuntu作業系統中以Ettus Research的API控制NI-USRP 2932接收訊號,透過開放計算語言(OpenCL)使用繪圖處理晶片其平行運算的能力進行加速,以對抗延遲的影響,實現實時的系統。 為驗證系統,結合上述射頻模組及軟體功能,實際展示傳收功能:在下行中,展示了2*2 real-time 15.36 MHz、over-the-air的實場測試;藉由展示,證實了OpenCL運用在非正交多工存取(NOMA)運算的可行性。 | zh_TW |
dc.description.abstract | Due to the rapid growth of mobile communication, wireless base stations are becoming a significant consumer of computational resources. In the future, most baseband signal processing will probably be centralized in baseband units using software to increase spectral efficiency and reduce operating costs. Due to the high parallel workloads, parallel computing is sutible for this situation. OpenCL is a framework for writing programs that execute across heterogeneous platforms to do parallel computing. In this thesis, we realize the NOMA baseband receiver by OpenCL.
We use the NI RF Modular Instruments as the transmitter to tansmit RF signal and the NI- USRP 2932 as the receiver to receive RF signal. Also, we utilize the API of Ettus Research to control the USRP 2932 in the Ubuntu enviromnet. Finally, we use the GPU that can run multi-threads to do parallel computing by OpenCL to speed up signal processing to resist latency to achieve downlink communication in real-time. To verify the system we developed, which combines the RF modules and software we have completed demonstration showing that over-the-air NOMA downlink data transmission and successful real-time reception of two patial streams at 15.36MHz sample rate and several power ratios. | en |
