Design and performance of an 8-dimensional modulation scheme

Hybrid Multi-Dimensional Modulation for Gaussian and Fading Channels

“…This method of creating a multidimensional 'super symbol' based on time division is however, wasteful in terms of bandwidth efficiency. Some possible implementation strategies for such a scheme are described in [4], for example, which is using four pulses and two carriers to generate eight dimensions space. Since the a-priori probabilities of these symbols are assumed to be equal, maximum likelihood decision rule is optimal for…”

“…The principle features of merit in MDM designs such as shaping gain and constellation expansion ratio were discussed in [2], [3]. Alternate way for implementation of multidimensional modulation schemes is discussed in [4]. An iterative MDM constellation design algorithm based on the behavior of charged particles in free space was presented in [5].…”

Multi-dimensional modulation for multi-path fading channels: Performance analysis
