Abstract(in Japanese) (See Japanese page)
Abstract(in English) In general, the modulation can be classified into the amplitude modulation(AM), the frequency modulation(FM), and the phase modulation(PM). The adaptive modulation system selects an appropriate modulation from these modulations against channel impairments. However, these modulations have a low degree of freedom or a small number of parameters to be optimized. The General Orthogonal Modulation(GOM) defines more flexible modulations [1],[2], with the modulation parameters of rotation plane and angle of a multi-dimentional space. In this paper, the error probability of GOM with Low-Density Parity-Check(LDPC) codes [3] is evaluated in the intersymbol interference(ISI) channel, and the modulation parameters are optimized in the channel.
