With the purpose of reducing the influenceof background noise on the call quality of mobile phones, background noisesuppression circuit is designed based on the principle of self-adaptive noisecancellation. Because this method is not involved in the nature of the noiseitself, it can be used both for stationary noise cancellation andquasi-stationary noise cancellation. The working principle and circuit designof the system are introduced in detail. Simulated experiment was conducted inthe lab, and its experimental results were analyzed. The experimental resultsshow that the circuit works well with low cost, and has a broad prospect ofapplication and popularization.
