| dc.description.abstract | 本論文是以DSP處理器來實現DVB-T發射機，利用BF533處理器來完整的實現一個OFDM符號中通道編碼的部分，包括RS碼(外編碼)、迴旋間插器(外間插)、迴旋碼(內編碼)、位元間插器和符號間插器(內間插)等發射機的部分。其中，DVB-T系統我們選擇2k模式來實現，在迴旋碼(內編碼)的編碼率上我們選用2/3的編碼率，在位元間插器和符號間插器(內間插)的部分我們選擇非階層傳輸16QAM之內間插來實現之。接著作16QAM映射和星雲圖，正確加入導引信號以及傳輸信號命令參數(TPS)，已完成DVB-T 2K模式之OFDM符框結構。 | zh_TW |
| dc.description.abstract | In this discussion, we use DSP processor to achieve a DVB-T transmitter, And we choose BF533 processor to achieve channel coding in a complete version of OFDM symbol, including Reed-Solomon Encoder (Outer Coding)、Convolutional Interleaver(Outer Interleaver)、Convolutional Encoder(Inner Coding)、Bit-wise Interleaver and Symbol Interleaver (Inner Interleaver)…etc. And in DVB-T system,we choose 2k mode to achieve. In Convolutional Encoder(Inner Coding),we choose code rate 2/3.In Bit-wise Interleaver and Symbol Interleaver (Inner Interleaver),we choose 16-QAM non-hierarchical transmission to achieve. And 16QAM mapping and Signal constellations, and insert pilots and TPS correctly, finally to implement OFDM frame structure in DVB-T 2K mode. | en_US |
