Modulated-carrier systems; Carrier systems characterised by combinations of two or more of the types covered by groups , , or; Amplitude- and phase-modulated carrier systems, e.g. quadrature-amplitude modulated carrier systems; Modifications of the signal space to increase the efficiency of transmission, e.g. reduction of the bit error rate, bandwidth, or average power in which the information is carried by both the individual signal points and the subset to which the individual points belong, e.g. using coset coding, lattice coding, or related schemes in which the constellation is the n - fold Cartesian product of a single underlying two-dimensional constellation
