PURPOSE:To obtain a transmitter-receiver for mobile communication capable of terminating a communication even under an intensive electric field by utilizing electric field information from a reception section. CONSTITUTION:The electric field information E from the 2nd IF section 66 of the reception section 6 is sent to a CPU section 72 via a control section 7, an A/D conversion section 74 and an interface section 73. The CPU section 72 reads out the electric field information E and a talking enable electric field level A decided in advance from a memory section 71 and gives them to a register of the CPU section 72. The electric field information E and the talking enable level X are compared, and when the level X is larger, an intensive electric field level B is read from the memory section 71 and compared with the electric field information E. If the electric field information E is larger than the intensive electric field level B, other level Aa in the memory section 71 stored in advance is selected from the level A and the similar comparison is implemented and even in the case of the occurrence of relation of E<X, E<B, the process is restored to the initial process and the similar processing is repeated. |
