摘要:
A receiver that receives a digital signal transmitted on the basis of an orthogonal frequency division multiplexing (OFDM) method. This receiver comprises a demodulation unit for demodulating the digital signal, a demapping unit for demapping demodulated data output from the demodulation unit, a frequency deinterleave unit for executing a frequency deinterleaving process on data output from the demapping unit, a delay unit for delaying control information superposed on the digital signal by a prescribed time period, and a time deinterleave unit for executing, on the basis of the interleave length specified by the control information delayed by the delay unit, a time deinterleaving process on data on which the frequency deinterleaving process has been executed.
