  • Bandwidth reduced multi carrier wireless transceiver and method thereof
    Patent number: 6549566
    Abstract: The present invention relates to a high efficiency Multi Carrier wireless transceiver and a method thereof. The object of the present invention is to provide the high efficiency wireless transceiver and a method thereof which reduces the transmission bandwidth to one half of required bandwidth in the wireless transceiver system using the Multi Carrier Code Division Multiple Access method. The present invention particularly relates to a wireless transceiving system using the Multi Carrier modulation method among high speed radio transmission technique, and has an effect of doubling the transmission efficiency in a system using a wired or wireless transmission channel by reducing the transmission bandwidth to one half of required bandwidth by using the symmetry of a Discrete Fourier Transformed signal. The present invention is used in the Multi Carrier wireless transceiver.
