Abstract
We have computed the 4-dimensional vectors of 16, 64, and 256-point with maximized minimum distance using the optimization technique. With the 4-dimensional vectors, we introduce two communication schemes, wireless optical communication scheme, and the 4-dimensional PSK modulators to improve performance. In wireless communication scheme, the 4-dimensional Multiple-Subcarrier Modulation with fixed bias achieves the normalized power requirements reduced to 1.8 dB, 2.6 dB, and 5.0 dB compared to those of the conventional schemes including QPSK, 8-PSK, and 16-PSK, respectively. In the 4-dimensional PSK modulators, up to 4.8 dB gain is obtained.
