Development of Transmitter and Receiver With Set Partitioning 64APSK Coded Modulation Designed on Basis of Channel Capacity

In this paper, we present a prototype transmitter and receiver with set partitioning (SP)-64 amplitude phase shift keying (APSK) coded modulation developed for expanding satellite transmission capacity. SP-multi-level is scheme that can improve noise immunity by properly combining scheme, bit allocation, error-correction codes. We designed SP-64APSK on the basis of channel capacity confirmed it has higher robustness to additive white Gaussian (AWGN) than DVB-S2X’s 64APSK Gray mapping through computer simulation. also implement our evaluated its performances in an AWGN non-linear simulating 12-GHz-band transponder characteristics. describe method designing simulation, modulation/demodulation process, receiver. indicate 8K ultra-high definition television (UHDTV) encoded rate 150 Mbps be transmitted using within 34.5 MHz, which bandwidth single broadcasting Japan.
