“…As discussed before, the constraints for Algorithms 1 and 2 are different and hence their results should be different thereupon. Similar to the A16QAM example presented in [15], both ultimate constellation subsets in Figures 2 and 3 will lead to the error probability improvements in the additive white Gaussian channels (AWGNs). This fact can easily be justified using [11].…”

Constellation subset selection is a new topic emerging in the adaptive modulation communications. How to choose the subset of the original constellation phasers appears to be challenging and interesting to the researchers. There hardly exists any literature which studies the feasibility and the solution of constellation subset selection in details. Here we dedicate to this problem in both theoretical exploration and algorithm design. In this paper, we introduce the detailed theoretical analysis regarding the mathematical properties of the commonly-used constellations and then facilitate the constellation subset selection problem. Based on our problem formulation, we design two algorithms to solve this problem thereby. Our complexity analysis evinces the effectiveness of the proposed algorithms. Index Terms-Constellation selection, symmetric constellation properties, adaptive modulation.This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE "GLOBECOM" 2009 proceedings.

“…Examples of π 2 -rotationally-invariant conjugate-symmetric constellations can be easily found everywhere in modern communication systems, such as 4 m -PSK, 4 m -QAM, m ∈ N [11], star-QAM [12], [13], [14], and A16QAM family [15].…”

“…Notice that the best 16APSK modulation from [6] could be added to the options of choice, since its CFM does not differ too much from the CFM attained by the 2r16APSK. 0.400 [4] Not applicable 16APSK [6], [7] 0.340 2.57 2r16APSK 0.325 1.61 A16QAM [3], [4] 0.268 [4] Not applicable 16APSK [6], [7] 0.260 3.15…”

“…It must be emphasized that constellation designs based on the generic APSK principle are not new [2]. Directly or indirectly motivated by this design strategy, many constellation alphabets have been proposed, developed under a variety of optimization criteria [3]- [7]. Table I summarizes exemplifying proposals, allowing for establishing the differences between them and the constellations developed herein.…”

In regard to the M-ary phase-shift keying (MPSK) modulation and the quadrature amplitude modulation (MQAM), MPSK is preferred up to M = 8, with MQAM being the most common choice for M > 8. In this letter, the modulations tworadii 8-ary and 16-ary amplitude-phase shift keying (APSK), respectively named 2r8APSK and 2r16APSK, are proposed as alternatives to 8PSK and square 16QAM, in this order. The 2r8APSK achieves higher power efficiency than the 8PSK, at the cost of a higher peak-to-average power ratio (PAPR) and a slightly more complex receiver. The 2r16APSK yields lower PAPR than the 16QAM, with roughly the same receiver complexity, but at the cost of a slightly lower power efficiency. Comparisons with other APSK-based modulations are made as well.
