    • PROBLEM TO BE SOLVED: To optimize radio communication between a fixed transmission/ reception base station and one mobile transmitter/receiver at least by determining an electric signal corrected by processing the electric signal inside a fixed base for respective antennas. SOLUTION: Concerning the respective antennas and respective radio telephone sets 5, a time function hi (t) being an impulse response corresponding to an antenna (i) and the consideration object telephone set 5 exists. Then, when an electric signal Si (t) is received from the telephone set 5 by the antenna (i) or transmitted from this antenna to the mobile equipment, inside a fixed base station 1, a corrected electric signal S'i (t) is determined corresponding to the convolution product S'i(t)=h'i(-t)*Si(t) of h'i (-t) and Si (t). The h'i (-t) is an approximate of the time inversion of impulse response hi (t) between the antenna (i) and the mobile equipment. When the signal Si (t) is a transmission signal, the signal S'i (t) is transmitted from the antenna (i) to the telephone set 5, but when that signal is a reception signal, it is received by the antenna of the base station 1 and synthesized with other signals.
