Abstract
En 中文
In communication systems, amplitude phase shift keying (APSK) arises as a potential solution to mitigate performance degradations due to channel non-linearities. Since it combines the characteristics of PSK and those of amplitude shift keying (ASK), APSK is also likely to be robust in systems influenced by phase noise. It is, therefore, solicited in cascaded systems involving visible light communications (VLC) as the second communication technology. This letter proposes the design of an APSK constellation, based on the kite structure, suitable for such cascaded systems. The constellation design is detailed and the symbol error probability is derived in closed-form. The bit error rate performance is compared with those of quadrature amplitude modulation (QAM) and PSK. Findings reveal that for 2 eta = 4 (eta being the common number of symbols per ring), the proposed APSK scheme has similar performance with QPSK and 4QAM, and, for 2 eta > 8, the APSK scheme outperforms the corresponding PSK, making it a good candidate for cascaded VLC systems. Even though the proposed scheme is outperformed by QAM, it gains up to about 5 dB over the PSK for an error rate of 10(-8).
