Abstract: In recent years，The use of infinite bet365 sports betting login sensor devices is becoming increasingly common，We are in a large-scale sensor network all the time。Compared to traditional microphone array，Wireless bet365 sports betting login sensor networks have many advantages，For example, it is not limited by the size of the application platform、Easy layout、Wider spatial perception range, etc.。At the same time，It also brings new challenges to speech signal processing，For example, network resources (battery energy、communication bandwidth) consumption、Time-varying topology、Device time synchronization, etc.。To this，We first proposed how to select a subset of microphones with the lowest energy consumption to achieve a specified speech noise reduction effect；Secondly，Since each device must be quantized before transmitting data，We propose how to optimally allocate network quantization rates；Again，Considering the poor robustness of centralized networks，We proposed a distributed speech noise reduction algorithm；Last，Because the traditional speech noise reduction algorithm based on beamforming requires the use of bet365 sports betting login transfer functions，We propose an bet365 sports betting login transfer function estimation method in low communication rate scenarios。
