Mobile communication device and channel quality collimating mark presumption manner

摘要

The mobile communication device and the channel quality collimating mark presumption manner which can do optimum channel quality collimating mark presumption treatment at the time of mobile communicating which uses TDD, are offered. From the threshold and difference of error it calculates the noise electricity of the reception signal and the estimator of the signal power the slot unit, on the frequency axis making use of the known signal which is included at the sub band unit which is the fixed frequency bandwidth which is continued on the time base, the multiple n which is presumed in the inside slot unit of estimator estimator, time it treats evenly in every sub band, calculates the error of time direction of the known signal at the slot unit, is beforehand decided of the slot where which among errors of time direction it adjoins, n in time average treating of time mean power calculation means presumptionThe respective weight factor of value is configurated.
