Orthogonal Frequency Division Multiplexing Receiver for Minimizing Inter-Symbol Interference

摘要

Techniques, apparatus, and systems are described for providing an orthogonal frequency division multiplexing (OFDM) receiving apparatus. An orthogonal frequency division multiplexing (OFDM) receiving apparatus includes a fast Fourier transform (FFT) start point estimating unit to detect a minimum symbol interference point of a received OFDM signal and identify a FFT start point. The apparatus includes a FFT operation performing unit to communicate with the FFT start point estimating unit and to perform a FFT operation at the FFT start point identified by the FFT start point estimating unit. The apparatus includes a phase modifying unit to communicate with the FFT start point estimating unit and to modify a phase of an output of the FFT operation performing unit. Also, the apparatus includes a decoding unit to communicate with the FFT operation performing unit and to decode the phase modified output of the FFT operation performing unit.
