The Development And Design Of Remote Voice Transmission System Based On Mobile Communication Network

With the continuous development of mobile communication network,The use of mobile communication network is also more and more extensive.At home,With the continuous expansion of the coverage of mobile communication networks,Signal quality and the continuous enhancement of the transmission rate.The mobile communication network provides a convenient and reliable transmission mode for the long distance transmission of the voice data.In practical applications,because of the high processing speed and high transmission bandwidth,the voice data transmission equipment cost is high.In some poor environment of mobile communication network,the remote voice transmission often has the phenomenon of instability.Some companies design and development of long-distance voice transmission products,such as large volume,poor portability,security and so on.In some special security areas of poor applicability,can not meet the actual needs of users.This topic is based on the analysis of different solutions and combined with the requirements of the subject design of a mobile communication network based on the remote voice transmission system.This system takes the AR9331 platform as the control core,and completes the processing of the speech.The data exchange between the client and the front end is completed through the relay server.Through the client to achieve the user’s control of the system.In order to achieve the above functions,In this paper,we first do a lot of research,and according to the requirements of the specific implementation of the program.Then it discusses the design of hardware circuit,the programming of the voice acquisition system,the design of the transfer service program,the client UI design and the client program design.And the whole system is tested according to the specific targets of the subject.Through testing,the design of the subject based on the mobile communication network of remote voice transmission system,achieved the basic functions of the voice remote transmission,achieve d the desired research purposes.This system has the characteristics of small size,low power consumption,convenient operation,high security,and has good application value.
