Design and implementation of AGC algorithm circuit for high PAPR signal
2016 International Conference on Integrated Circuits and Microsystems (ICICM)(2016)
摘要
This paper presents an automatic gain control (AGC) algorithm and circuit used in wireless communication receivers with high peak power to average power ratio (PAPR) signal. Combining fixed gain amplifier and programmable attenuator, the AGC function can be implemented by comparing the strength of thresholds with reading two points power detection value of radio frequency (RF) signal. The proposed method can well solve the gain jitter problem in the gain control procedure, implement gain control for each frame of input signal, and shut off the input signal channel if the SNR of input signal is small.
