Abstract

A wireless reception device, a wireless sending device, and a wireless transmitting device are provided, wherein occurrences of distortion and an error in the radio signal that is being transmitted can be prevented even if compensation for circuit characteristics is performed.

The wireless reception device writes a reception parameter into reception parameter memory means for renewal, only when a predetermined renewal condition is satisfied. The wireless reception device generates a reception characteristic control signal, on the basis of a reception parameter which is stored in the reception parameter memory means. The wireless sending device writes a sending parameter into sending parameter memory means for renewal, only when a predetermined renewal condition is satisfied. The wireless sending device generates a sending characteristic control signal, on the basis of a sending parameter which is stored in sending parameter memory means.

Claims

1. A wireless reception device for generating a reception parameter and controlling its characteristic on the basis of a generated reception parameter, comprising:

reception means for receiving a radio signal by a reception characteristic which corresponds to a reception characteristic control signal;

reception parameter generating means for generating said reception parameter;

reception parameter memory means for storing said reception parameter;

reception parameter writing means for writing a reception parameter which is generated by said reception parameter generating means into said reception parameter memory means for renewal so as to renew said reception parameter; and

reception control means for generating said reception characteristic control signal on the basis of a reception parameter which is stored in said reception parameter memory means,

wherein said reception parameter writing means writes said reception parameter into said reception parameter memory means for renewal only when a predetermined renewal condition for a reception parameter is satisfied.

2. The wireless reception device according to claim 1, wherein said predetermined renewal condition for a reception parameter is that the radio signal is not being received by said reception means.

3. The wireless reception device according to claim 2, wherein said renewal condition for a reception parameter includes that a period more than a minimum renewal interval has elapsed since a previous renewal of a reception parameter.

5. The wireless sending device according to claim 3, wherein said predetermined renewal condition for the sending parameter is that a radio signal is not being sent by said sending means.

6. The wireless sending device according to claim 5, wherein said renewal condition for the sending parameter includes that a period more than a minimum renewal interval has elapsed since a previous renewal of a reception parameter.

4. A wireless sending device for generating a sending parameter and controlling its characteristic on the basis of a generated sending parameter, comprising:

sending means for sending a radio signal by a sending characteristic which corresponds to a sending characteristic control signal;

sending parameter generating means for generating said sending parameter;

sending parameter memory means for storing said sending parameter;

sending parameter writing means for writing a sending parameter which is generated by said sending parameter generating means into said sending parameter memory means for renewal; and

sending control means for generating said sending characteristic control signal on the basis of a sending parameter which is stored in said sending parameter memory means,

wherein said sending parameter writing means writes said sending parameter into said sending parameter memory means for renewal only when a predetermined renewal condition for a sending parameter is satisfied.

7. A wireless transmitting device having:

a wireless reception device for generating a reception parameter and controlling its characteristic on the basis of the generated reception parameter; and

a wireless sending device for generating a sending parameter and controlling its characteristic on the basis of the generated sending parameter,

wherein said wireless reception device comprising;

reception means for receiving a radio signal by a reception characteristic which corresponds to a reception characteristic control signal;

reception parameter generating means for generating said reception parameter;

reception parameter memory means for storing said reception parameter;

reception parameter writing means for writing a reception parameter which is generated by said reception parameter generating means into the reception parameter memory means for renewal; and

reception control means for generating said reception characteristic control signal on the basis of a reception parameter which is stored in said reception parameter memory means,

wherein said wireless sending device includes;

sending means for sending a radio signal by a sending characteristic which corresponds to a sending characteristic control signal;

sending parameter generating means for generating said sending parameter;

sending parameter memory means for storing said sending parameter;

sending parameter writing means for writing the sending parameter which is generated by said sending parameter generating means into said sending parameter memory mean for renewal; and

sending control means for generating said sending characteristic control signal on the basis of a sending parameter which is stored in said sending parameter memory means,

wherein said reception parameter writing means writes said reception parameter into said reception parameter memory means for renewal only when a predetermined renewal condition for the reception parameter is satisfied, and

wherein said sending parameter writing means writes said sending parameter into said sending parameter memory means for renewal only when a predetermined renewal condition for the sending parameter is satisfied.

8. The wireless transmission device according to claim 7, comprising:

said predetermined renewal condition for the reception parameter is that a radio signal is not being received by said reception means.

9. The wireless reception device according to claim 8, wherein said renewal condition for the reception parameter includes that a period more than a minimum renewal interval has elapsed since a previous renewal of a reception parameter.

10. The wireless transmission device according to claim 9, wherein said predetermined renewal condition for the sending parameter is that a radio signal is not being sent by said sending means.

11. The wireless transmission device according to claim 10, wherein said renewal condition for the sending parameter includes that a period more than a minimum renewal interval has elapsed since a previous renewal of a sending parameter.
