| 发明名称 | Method and apparatus for adaptive automatic gain control | ||
| 摘要 | Systems and methods for dynamically adjusting the gain in a receiver front end to have a desired amount of headroom, based upon a measurement of the signal to noise ratio (SNR) of the output of a digital to analog converter and the amount of degradation to the SNR due to previous adjustments to the gain. | ||

| 主权项 | 1. A receiver front end comprising: a) an automatic gain control (AGC) module having an input and an output; b) an analog to digital converter (ADC) having an input and an output, the input coupled to the output of the AGC module; and c) an AGC control module having an input for receiving information regarding the signal output from the ADC and an output for controlling adjustments to the gain of the AGC module, the AGC control module reducing the gain of the AGC module in increments so long as the Signal to Noise Ratio (SNR) is above a minimum level. | ||
