The radio frequency (RF) front-end gain plays a crucial role since it determines the communication sensitivity and anti-interference performance, especially in the presence of both high-power interference signals and weak communication signals. In this paper, the influences of the RF front-end gain on communication sensitivity as well as interference cancellation ratio (ICR) are thoroughly analyzed. Thereinafter, we derive the mathematical model of the RF front-end gain constrains taking communication sensitivity, ICR requirement and analog-to-digital converter quantization accuracy into consideration. Based on the upper and bottom boundaries gain analysis, we propose the gain design criterion for adaptive interference cancellation in communication systems. Extensive simulations demonstrate that: 1) the ICR performance improves with the increase of RF front-end gain when lower than the gain obtained from upper boundary analysis, and is saturated afterward; 2) the gain obtained from bottom boundary analysis can ensure the communication sensitivity. Experimental results verify that the gain design criterion ensures the communication sensitivity and satisfies the requirements of anti-interference performance under high-power interference signals.
