摘要
基于MINI2440 ARM平台实现了无线局域网语音通信,主要完成了语音数据的采集、编码、压缩及实时传输。采用Qt/Embedded跨平台应用程序和UI开发框架实现了嵌入式通信软件的界面、网络及多线程编程。采用G.729B编解码算法实现语音数据的编码及压缩,并对该算法进行了优化来减少其复杂度。
Voice communication over wireless local area network based on MINI2440 platform is implemented, including the acquisition, encoding, compression and real-time transmission of voice data. Qt/Embedded cross-platform application and UI development framework are used to achieve the interface, network and multi-threaded programming of embedded communications software. The encoding and decoding of voice data is achieved by G.729B algorithm, and the algorithm is optimized to reduce its complexity.
