This paper presents the amplitude phase shift keying (APSK) modulation application for SCMA codebook design. The APSK modulation is the corner stone to all QAM modulation schemes, as QAM employs amplitude variations and phase variations. The modulation scheme has found favour among researchers and industry such as digital broadcasting for satellites (DVB-S2). It is important to note the importance of the selection made as satellites have limitations in power and providing reliable communication. Thus, in this paper the optimization method incorporates the optimum RR principle. Hence, the effect of ring ratio on the system performance, such as the BER and PAPR is considered in this paper.

摘要

This paper presents the amplitude phase shift keying (APSK) modulation application for SCMA codebook design. The APSK modulation is the corner stone to all QAM modulation schemes, as QAM employs amplitude variations and phase variations. The modulation scheme has found favour among researchers and industry such as digital broadcasting for satellites (DVB-S2). It is important to note the importance of the selection made as satellites have limitations in power and providing reliable communication. Thus, in this paper the optimization method incorporates the optimum RR principle. Hence, the effect of ring ratio on the system performance, such as the BER and PAPR is considered in this paper.
