1. A method for transmitting a signal, the method comprising
transforming a signal into a frequency domain to acquire a spectrum;
forming a filtered spectrum according to a filter spectrum;
transforming a frequency domain representation of an Orthogonal Frequency Division Multiplex (OFDM) signal, the frequency domain partially occupied with the filtered spectrum, into a time domain to acquire a temporary signal; and
subjecting the temporary signal to a phase modulation to obtain a phase modulated temporary signal;
wherein the temporary signal is subjected to a continuous phase modulation comprising a minimum shift keying.
