Data series are stored at multiple resolutions in a computer-readable data storage medium. In particular, time series data values of the data series are received with associated timestamps. Corresponding storage elements in the computer-readable data storage medium are identified based on the time stamps. Aggregate values are determined by summing the time series data values. The time series data values stored in the corresponding storage elements are replaced by the aggregate values. Combined data values of the aggregate values are stored in storage elements in the computer-readable storage medium at a first resolution and second resolution, where the second resolution is half of the first resolution.

The DFT 12 converts a modulated digital signal into a spectrum of a frequency band. A use frequency band notification unit in a reception device notifies a transmission device 1 of a use frequency band. A deletion unit 141 in the transmission device 1 deletes a spectrum of a band other than the use frequency band after shaping of a spectrum waveform based on the water filling principal by a shaping unit 13. Then, a digital signal for each data series concerning the spectrum obtained after deletion by the deletion unit 141 is synthesized by a synthesizing unit 16 and sent from the transmission device 1 to the reception device. A reception side conversion unit in the reception device converts the digital signal sent by the transmission unit into a spectrum of a frequency band. A turbo equalization unit performs turbo equalization on the converted spectrum.
