Patent granted for distributed antenna system with digital-analog expansion
A recently granted patent (Publication Number: US11923905B2) discloses a distributed antenna system comprising at least two digital-analog expansion units and remote cascade chains. Each digital-analog expansion unit is connected to a remote cascade chain, with the system designed to perform baseband processing operations on digital radio frequency signals for transmission through optical fibers. The system allows for analog-to-digital and digital-to-analog conversions, enabling seamless signal transmission between remote units and terminal devices. The patent also details a signal transmission method within the system, involving the combination of analog radio frequency signals and digital processing for efficient data transmission.
Furthermore, the patent outlines a gain control method and apparatus for the distributed antenna system. The gain control method involves measuring radio frequency signals transmitted by the digital-analog expansion unit to determine power values and cable lengths, facilitating optimal signal transmission. The gain control apparatus, integrated into each remote unit, includes modules for power measurement, cable length acquisition, and attenuation value matching. These components work together to ensure precise control over signal gain and transmission quality within the distributed antenna system, enhancing overall performance and efficiency in signal processing and distribution.
