AI Technical Summary
In existing technologies, digital filtering schemes are costly and have long delays, while traditional analog filtering schemes cannot effectively suppress adjacent carriers, resulting in high costs for repeater equipment and difficulty in flexibly adjusting carrier combinations.
A carrier shutdown method based on analog filtering is adopted, which uses an analog filter to filter the radio frequency channel. The amplifier is turned on or off independently by control commands to amplify or suppress a specific carrier. The transition band width of the analog filter is widened to half the bandwidth of the adjacent carrier to reduce the design difficulty.
It achieves low-cost, low-latency carrier shutdown, reduces system complexity and power consumption, supports flexible carrier combination control, reduces equipment costs and maintenance investment, avoids local oscillator leakage problems, and improves signal purity.
