Transmitting/receiving apparatus method for fast frequency hopping in orthogonal frequency division multiplex system and method therefor

The present invention relates to a transmission and reception apparatus for performing fast frequency hopping unit of the sample time (FFT) in an orthogonal frequency division multiple access (OFDM) system. A transmission apparatus, a transmission signal consisting of the data elements of the input data vector to the linearized group, a plurality of samples with the new data vector inverse fast Fourier transform to transform to output new data vector according to the frequency hopping pattern of a sample unit of time It consists of the vector to the inverse fast Fourier transformer for output. Reception apparatus, frequency hopping received signal vector in the second received signal vector of the frequency-domain fast Fourier transform the first equalizer, said multiplying the FFT, and the inverse matrix of a channel matrix representing channel characteristics for the received signal vector the equalizer output is 1 consists of a frequency hopping restoring and outputting the received signal vector restored by multiplying the frequency hopping of the restoration matrix. This invention by increasing the reception success probability due to frequency diversity effect improves the performance of the overall system.
