Title:
RECEIVER AND AUTOMATIC GAIN CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/205558
Kind Code:
A1
Abstract:
Provided is a receiver in which an AGC circuit (20) includes a saturation level detection unit (23), a gain setting unit (22), a gain adjustment unit (21), and a parameter setting unit (24). The saturation level detection unit (23) detects the saturation level of a digital signal output from an A/D converter (10). The gain setting unit (22) sets the gain used in adjustment of the amplitude level of the digital signal on the basis of the saturation level detected by the saturation level detection unit (23). The gain adjustment unit (21) adjusts the amplitude level of the digital signal in accordance with the gain set by the gain setting unit (22). The parameter setting unit (24) sets a parameter used in the saturation level detection unit (23) on the basis of the amplitude level of the digital signal output from the A/D converter (10).
