ACI-Aware Receiver Gain Control for Adjacent-Channel Saturation

The patent segments the amplitude analysis into two distinct components: average amplitude determination (for overall signal level control) and abnormal amplitude detection (for ACI interference identification). By separating these functions and analyzing them independently, the system can maintain accurate average amplitude measurement while simultaneously detecting and handling abnormal amplitude values that would otherwise cause distortion.

The patent performs preliminary detection of abnormal amplitude values before they cause distortion. By identifying abnormal amplitudes in advance and adjusting the gain accordingly, the system prevents amplitude saturation from occurring in the first place, thereby maintaining signal integrity without waiting for distortion to manifest.

The patent implements a feedback mechanism where the detected presence of abnormal amplitude values feeds back to the gain determination process. When abnormal amplitudes are detected, the system adjusts the gain downward to prevent amplitude saturation, creating a closed-loop control system that dynamically balances signal amplification with distortion prevention based on real-time signal conditions.

The patent dynamically changes the gain parameter based on the detected signal conditions. Instead of using a fixed gain or gain based solely on average amplitude, the system modifies the gain parameter in response to abnormal amplitude detection, thereby adapting the amplification level to prevent both weak signal loss and amplitude saturation.

The patent makes the gain determination dynamic by incorporating real-time detection of abnormal amplitude values. The gain is not fixed or based solely on average amplitude, but dynamically adjusted according to the presence and severity of ACI interference, allowing the system to optimize between signal amplification and distortion prevention based on current signal conditions.

The patent changes the gain parameter adaptively based on detected signal characteristics. When abnormal amplitudes are present, the gain is reduced to prevent saturation; when abnormal amplitudes are absent, the gain can be increased to improve signal amplification. This dynamic parameter adjustment resolves the contradiction between maintaining signal integrity and achieving adequate amplification.
