Transmitting apparatus, receiving apparatus, communication system, and communication method

摘要

A transmitting apparatus includes a group processing unit configured to divide plurally data of one block, control processing units configured to perform predetermined control processing for each of the divided data, a combination processing unit configured to combine the data subjected to the control processing into one signal, a transmission processing unit configured to apply predetermined transmission processing to the combined signal to convert the signal into a transmission signal, and a control-signal generating unit configured to retain a predetermined number of control value candidates, one set of which includes M control values used in the control processing carried out by the control processing units, and select, as a selected candidate, one of the control value candidates based on power information of the transmission signal, and generate M control signals corresponding to the selected candidate and input the control signals to the control processing units.

1. A transmitting apparatus comprising:
circuitry including: a data dividing circuitry portion configured to divide data of one block into M divided data, M being equal to or larger than 2; M Fourier transform circuitry portions configured to perform Fourier transform processing for each of the M divided data and generate M data subjected to Fourier transform; M control processing circuitry portions configured to apply predetermined control processing to each of the M data subjected to the Fourier transform and generate M data subjected to the control processing; a combination processing circuitry portion configured to apply inverse Fourier transform processing to the M data subjected to the control processing and combine the M data subjected to the control processing into one signal; a transmission processing circuitry portion configured to apply predetermined transmission processing to the combined signal to convert the signal into a transmission signal; a candidate selecting circuitry portion configured to retain a predetermined number of control value candidates, one set of which includes M control values used in the control processing carried out by the M control processing circuitry portions, and select, as a selected candidate, one of the control value candidates based on power information of the transmission signal; and a control-signal generating circuitry portion configured to generate M control signals for setting the M control values included in the selected candidate respectively in the control processing circuitry portions corresponding thereto and input the control signals respectively to the control processing circuitry portions corresponding thereto.
