Abstract
A communication apparatus includes a Doppler shift amount calculation unit configured to calculate a Doppler shift amount of a reception signal which is obtained by modulating a signal, for which spectrum spreading is performed by using a predetermined spread code, by a predetermined carrier frequency, a frequency shift amount setting unit configured to set a frequency shift amount on the basis of the Doppler shift amount, a frequency conversion unit configured to shift the frequency of the reception signal by the frequency shift amount, a coherent addition unit configured to perform coherent addition of the reception signal, a spread code generation unit configured to generate a spread code, and a phase detection unit configured to perform correlation calculation between a calculation result of the coherent addition and the spread code and detect a phase of the spread code of the reception signal on the basis of the correlation calculation result.
