SYSTEM AND METHOD FOR PERFORMING FAST TRANSMISSION OUTPUT POWER TRANSITION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17943399 titled 'SYSTEM AND METHOD FOR PERFORMING FAST TRANSMISSION OUTPUT POWER TRANSITION
Simplified Explanation
The patent application is directed towards compensating for gain drift in a transmitter of an electronic device, specifically in cellular network applications where the transmit power level may be frequently adjusted. To address the issue of gain increase during low power symbols, a gain compensation signal is introduced into the transmitter, which can be adjusted and refined through a power control loop.
- Introduction of gain compensation signal to mitigate gain increase during low power symbols
- Implementation of power control loop to adjust and refine the compensation signal
Potential Applications
The technology could be applied in various wireless communication devices such as smartphones, tablets, and IoT devices where transmitter power levels need to be adjusted frequently.
Problems Solved
1. Distortion of transmission signal due to gain drift during power level switching 2. Undesirable gain increase during low power symbols
Benefits
1. Improved signal quality and reliability 2. Enhanced performance of the transmitter 3. Reduction of signal distortion and interference
Potential Commercial Applications
Optimizing transmitter performance in cellular network devices Enhancing signal quality in wireless communication devices
Possible Prior Art
One possible prior art could be the use of automatic gain control (AGC) techniques in transmitters to adjust gain levels based on input power variations.
Unanswered Questions
How does the power control loop adjust the gain compensation signal?
The power control loop may use feedback mechanisms to monitor the output power and adjust the compensation signal accordingly.
What impact does the gain compensation signal have on overall power consumption?
The gain compensation signal may lead to slight increases in power consumption due to the adjustments made to maintain signal quality.
Original Abstract Submitted
This disclosure is directed to compensating for gain drift due to switching the output power of a transmitter of an electronic device. In some cellular network applications, the transmit power level of a transmitter may be frequently adjusted from a low power level to a high power level. If the power level is not switched to the desired power level within a given interval, the transmission signal may be distorted. To enable the transmitter to reach a desired output power within the interval, the voltage supply of a power amplifier may be raised during a low power symbol, which may produce an undesirable gain increase. To mitigate or eliminate the low power symbol gain increase, a gain compensation signal may be introduced into the transmitter. The compensation signal may be adjusted and refined by implementing a power control loop, the power control loop may include a power controller.
