  • Apparatus, and associated method, for transforming data in an OFDM communication system
    Patent number: 6940828
    Abstract: Apparatus, and an associated method, for facilitating communications in an OFDM communication system. A sending station of the OFDM communication system performs inverse discrete trigonometric transforms upon modulation symbols representative of data that is to be communicated. And, a transformed vector is formed by the inverse discrete trigonometric transformer. A symmetric extension adder adds an extension to the transformed vector to attain desired symmetry or anti symmetry properties. The apparatus formed at a receiving station of the OFDM system includes a discrete trigonometric transformer for performing transform operations upon data received thereat.
