摘　　要：基于ARM-LINUX的嵌入式平台和CDMA网络,采用GSM算法对音频数据编解码,设计显式连接的UDP套接口模式传输压缩后的音频数据,并通过上层编程保证了其可靠性,引入了"生产者消费者"模型来解决线程间的同步问题。最终在资源受限的嵌入式平台上完成了高性能、低成本的便携音频通信系统。This paper uses GSM Algorithm to encode and decode audio data based on ARM-LINUX embedded platform and CDMA network.It also design of the explicit UDP socket connection mode to transmit the compressed audio data,and ensure its reliability through top programming.The introduction of＂producer consumer＂model is used to solve the problem of synchronization between threads.Finally,a high-performance,low-cost portable audio communication system is realized on the resource-constrained embedded platforms.
