A method and a receiver are provided for demodulating a received multi-carrier modulated signal. The demodulation procedure includes (a) multiplying the received multi-carrier modulated signal with its complex conjugate to obtain a squared signal; (b) multiplying the squared signal with a signal having a frequency 2  &pgr; T to obtain a product signal, where T represents a duration of a symbol in the received multi-carrier modulated signal; and integrating the product signal over the duration T. The signal having a frequency 2  &pgr; T may be a complex signal having the form exp  ( j   2  &pgr; T  t )   or   exp  ( - j   2  &pgr; T  t ) , , or a cosinusoidal signal having the form cos  ( j   2  &pgr; T  t ) , , according to whether the multi-carrier modulated signal is a complex signal or a real signal. |
