1Loss of information
If antenna parameters are transferred via a radio channel or induction connection channel, then antenna identification data can be transmitted to the microprocessor, but an additional channel is required which makes implementation difficult when both a service channel and a main data channel exist within a system
Solution Approach 1:
The patent combines antenna identification data transmission with the existing service channel by modulating the service channel signal. Instead of creating a separate communication channel, the invention merges the identification data transfer function into the existing signal path used for service data, thereby eliminating the need for additional channels while maintaining reliable data transmission
Solution Approach 2:
The service channel is made multi-functional by enabling it to carry both its original service data and the antenna identification parameters simultaneously through signal modulation. This universal approach allows a single channel to perform multiple functions, reducing overall system complexity while ensuring complete information transfer

AI summary
Antenna identification data is transferred over a regular channel that is normally used for transferring navigation signals. Modulation of the received signal is used for transferring the portable antenna parameter data. Antenna identifications and parameters are written into a portable antenna module. The antenna module is attached to a radio receiver. The antenna module and the receiver are powered up. The portable antenna module receives radio signals that are amplified in a low-noise amplifier. Then, a level of the output signal is discretely modulated in the amplitude modulator and the signal is transferred to the radio receiver. The discrete fluctuations of the level of the signal are determined in the amplitude demodulator. The fluctuation of the level of the signal carries the information about the identification parameters of the portable antenna module. An analog-to-digital conversion of the determine signal fluctuation is performed in an analog-to-digital converter. The converted digital signal is used for receiving data related to the type and parameters of the portable antenna module.
