Abstract(in English) | In this paper, we propose new modulation schemes in multi-dimensional Euclidean space under the condition that all symbols are on a hypersphere. In the proposed symbol design, the symbols are assigned on vertices of a twisted and crushed hypercube. Moreover, it is possible to generalize the proposed symbol designs to any dimension. The minimum symbol distance of the proposed design grows with the increasing number of dimensions in comparison with the conventional QPSK. By theoretical analysis based on a upper bound and computer simulations, we show that the proposed symbol design in 8-dimensional space can reduce the required $E_b/N_0$ by more than 0.8 dB at $10^{-7}$ of the BER. |
