Abstract(in English) Aiming at the realization of "Super Hi-Vision (4K/8K)" Satellite News Gathering (SNG), we are studying an improvement of Forward Error Correction (FEC) and implementation of Multilevel Coded (MLC) Modulation. In this paper, we have evaluated 16QAM using Set Partitioning (SP), which can increase the minimum euclidean distance by separating bits in each symbol with the SP mapping rule. Under the constant code rate of 7/9, we adjust LDPC code rate in each bit and introduce the combination of code rate having the best transmission performance under the AWGN by computer simulation. We show that the required C/N of proposed SP-16QAM is 0.4dB better than 16APSK (7/9) of ARIB STD-B44 and DVB-S2X under the AWGN.
