  • Patent number: 10305630
    Abstract: An object is to suppress a decrease in communication quality and improve the communication quality even when interference is present in some of a frequency band in use in a case where a turbo coding scheme is combined with multicarrier communication using some of a frequency band shared with another system. A frequency selector (107) selects a band not used by another system, based on a measurement value of a reception level, then selects a subband for systematic-bit mapping from among subbands having a measurement value of the reception level lower than a threshold, and selects a subband for parity-bit mapping from among subbands other than the subband for systematic-bit mapping, for each subband (carrier frequency) of the selected band. A carrier-mapper (110) maps a systematic bit and parity bit to each subband based on the result of selection by the frequency selector (107).

  • Patent number: 10294521
    Abstract: The present disclosure provides a measurement method of telomerase activity with no occurrence of false-negative and high quantitative capability. In the measurement method of telomerase activity of the present disclosure, a solution containing telomerase as a sample solution is mixed with a solution containing primer DNA as a substrate for telomerase even as or after a solution containing non-primer DNA not as a substrate for telomerase is mixed therewith. Non-primer DNA can remove an effect of DNase in the sample solution and prevent occurrence of false-negative. Subsequently, the primer DNA is extended with the telomerase and the extended primer DNA is detected, through which telomerase activity is measured.
