シングルキャリア方式パラメータの最適値検出装置及びプログラム

Japanese Patent JP7316099

B2

To provide an optimum value detection device and a program for detecting an optimum value of a parameter related to a single carrier type transmitting device and a receiving device without relying on simulation and with high accuracy.SOLUTION: An optimal value detection device 3 according to the present invention includes a C/N controller 31 that variably controls a received C/N in a receiving device 2 by adjusting a load on a modulated signal output from a transmitting device 1, and a parameter controller 32 that performs variable control of parameter settings related to one or both of a boost ratio of a pilot signal consisting of unique words for the transmitting device 1 and the amplitude and phase of the mapping for each modulation method, notifies the receiving device 2 of the setting information of the boost ratio, obtains required C/N for each parameter to be variably controlled while variably setting the C/N setting for the C/N controller 31 on the basis of the bit error rate information from the receiving device 2, and detects an optimum value of the parameter.SELECTED DRAWING: Figure 1
