Abstract
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 carrier demodulating signal to obtain a product signal, and integrating the product signal over the duration T. A bit decision may then be performed on the integration result using analog components without the need for high-speed analog-to-digital conversion.
