In the above figure, M=4 for each symbol. These modulation schemes are often referred to as linear since they require linear amplification. 16-QAM has the largest distance between points but needs very linear amplification. 16PSK has less strict linearity requirements but has less spacing between constellation points, making it more susceptible to noise. M-ary schemes […]
