Title DVB-T TX Implementation with DSP Processor
Date of Defense 2006-07-05
Page Count 72
Keyword
  • DSP Processor
  • DVB-T TX
  • 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.
