Abstract： |
A cascading error correction coder and its coding method can be used in ground data multimedia television broadcast system. It takes the error correction coding planisphere and modulation mapping planisphere as a whole to be considered to finished the net lattice coding modulation and then to realize the coding and the mapping after coding according to certain format for greatly raising the system performance in its error correction and transmission. The said net lattice coding modulation pattern can be cecular QPSK, turbo cecullar QPSK, cecullar 16 QAM, turbo cecullar 16 QAM, cecullar 64 QAM, turbo cecullar 64 QAM and etc. |
