Shift space-time coding for digital video broadcasting systems |
摘要 |
A shift space-time encoding scheme applies STBC over hierarchical modulation. A low-priority bit stream is modulated to complex symbols using STBC encoding and a high-priority bit stream is modulated to complex symbols without STBC encoding. Complex symbols from the low-priority bit stream together with the complex symbols from the high-priority bit stream are added to form a hierarchical 64-QAM constellation.
