CH-SETTING AUTOMATIC CHANGE METHOD FOR AGILE OFDM-SP AND AGILE OFDM-SP WITH CH-SETTING AUTOMATIC CHANGE FUNCTION

摘要

PPROBLEM TO BE SOLVED: To solve the problem that a conventional CH-setting change requires time and effort, and when an OFDM is located at the top of a mountain or in a remote place, the operation in situ, consequently, is troublesome and very expensive. PSOLUTION: Channel (CH) data before repacking are stored in an OFDM-SP unit of an agile OFDM-SP. After that, the presence of an input signal is detected for each CH while receiving input signals of stored multiple CHs by the OFDM-SP unit. When the input signal of any one of the CHs is not detected, the received CH data are compared with the previously-stored CH data. Subsequently, when new CH data are detected without detecting any one of the CH data in the CH data before repacking, it is determined that the CHs are repacked, and then, the setting of input CHs of the OFDM-SP unit is automatically changed to the CH data after repacking.
