Abstract

In this paper, a modulation identification method of block orthogonal modulations is proposed. The identification method is based on General Orthogonal Modulations (GOM), whose modulation parameters should be estimated. Basis vectors are obtained from received signals, and are used to estimate the parameter of GOM. Moreover, we propose demodulation method using basis vectors. Bit error rate of the identified modulation is evaluated in an additive white Gaussian noise channel by computer simulations.
