To provide a transmitter-receiver apparatus for fast frequency hopping in an orthogonal frequency division multiple connection system.
A transmitting apparatus includes a transformed inverse fast Fourier transformer to inverse-fast-Fourier-transform an input data vector and to output a transmission signal by further multiplying a prescribed gain by a cyclic frequency hopping pattern, and a receiving apparatus includes a first fast Fourier transformer to fast-Fourier-transform a frequency-hopped receiving signal vector into the receiving signal vector in a frequency region, an equalizer to multiply an inverse matrix of a channel characteristic by the receiving signal vector, the transformed inverse fast Fourier transformer to fast-Fourier-transform an output of the equalizer and to output the prescribed gain corresponding to the cyclic frequency hopping pattern of the transmitting apparatus further by multiplying, and a second fast Fourier transformer to fast-Fourier-transform the output of the transformed inverse fast Fourier transformer.
