ABSTRACT:
A transmission method for transmitting signals on the basis of an orthogonal frequency division multiplex (OFDM) system is disclosed. Information to be transmitted in the signals is modulated onto a number of subcarriers in the frequency domain according to an OFDM modulation method, the information including phase reference information and power control information. One of the subcarriers is a phase reference subcarrier that carries the phase reference information. The power control information is modulated onto the phase reference subcarrier, thereby improving transmission efficiency. The signals are transformed into the time domain, and then transmitted.
