PROBLEM TO BE SOLVED: To provide a device which executes more suitable transmission power control without depending on the speed of fading fluctuation by forming one tine-sequential signal with a known signal in a prescribed period and a previous known signal, linearly predicting and analyzing the time-sequntial signal, calculating the average power of the signal in the prescribed period and setting it as the average reception power of a desired signal component. SOLUTION: The reception signal received by a reception antenna 21 is converted into the signal of a diffusion band by a high frequency part 22 and is decoded as a bas band signal by inverse diffusion parts 31-33. Decoded outputs from the inverse diffusion parts 31-38 are respectively inputted to transmission line prediction parts 41-43 and intra-slot interference noise power calculation part 60. A signal power calculation part 50 calculates a signal power estimation value by using transmission line prediction values outputted from the transmission line prediction parts 41-43. The intra-slot interference noise power calculation part 60 calculates interference noise power in a slot and the output is inputted to an inter-slot average interference noise power calculation part 70. Then, a final interference noise power estimation value is calculated. |
