Bandwidth reduced multi carrier wireless transceiver and method thereof

A reduced bandwidth Multi Carrier transceiving method using the symmetry of Inverse Fourier Transformed signal comprising the steps of:

• a first step in which a serial/parallel conversion section converts externally input serial signals into parallel signals;
• a second step in which an Inverse Fast Fourier Transform (IFFT) section Inverse Fourier Transforms the plurality of parallel signals transmitted from said first serial/parallel conversion means, divides the signals into data sequences of real part and imaginary part, and outputs the signals by reducing the number of channels;
• a third step in which a transmission processing section converts the output signal of said IFFT section into analog signal and transmits the signal by modulating the signal;
• a fourth step in which a reception processing section demodulates the signal transmitted from said transmission processing means and thereafter converts the demodulated signal into digital signal;
• a fifth step in which a high frequency signal generation section receives the output signal of said reception processing means and generates the high frequency signal;
• and
• a sixth step in which a signal recovery section receives the output signal of said high frequency signal generation means and outputs the original serial data.
