程序应该是自已explainatory如果不，用户手册是attacted。 原始代码被评论。 文件附有了： phonev2a.c -原始代码， phonev2a.exe -二进制文件， samdb.txt -样品数据库文件， userm2a.doc -用户手册。-The program should be self-explainatory if not,a user manual has been attacted. source code are commented. Files attached: phonev2a.c- source code, phonev2a.exe- binary file, samdb.txt- sample database file, userm2a.doc- user manual.

2.0说明 1.0支持系统的录音多种格式,有一定的延时,没有过滤杂音功能. 2.0已取消支持系统的录音多种格式,使用PCM采集数据G711A压缩格式(8000HZ单声道16位格式录音每秒以8K完成数据,16000HZ单声道16位格式录音每秒以11K完成数据,音质相当好),延时降低到最小100-500MS以内,不会随时间增加而增加延时(如果是说话测试一直保持200MS的延时,如果是用播放歌曲来测试,有自动校正延时功能,恢复成200MS的延时,恢复过程中不会中断歌曲的播放,只是小小加快唱歌的速度,听觉不会觉察出来),加入了过滤杂音功能. 2.0安装 将ACMG711.dll复制到系统文件夹里 再安装控件 -2.0 1.0 Note recording system to support multiple formats, a certain delay, no noise filtering function. 2.0 support system has been abolished recording formats, the use of PCM data acquisition G711A compression format (8000HZ 16 mono recording format to 8K per second complete data 16000HZ mono recording format 16 to 11K per second complete data quality is very good), Delay reduced to the minimum 100-500MS within not with time delay increases (if word has been tested 200MS delay, If it is used to test play the songs, the automatic correction function of delay, 200MS resume into the delay, the recovery process will not be interrupted play songs, singing just a small speed up

本文主要研究了W-WAN中GPRS网络的移动视频传输问题。文中探讨了GPRS的网络结构、协议体系以及链路特性，从中我们看出： GPRS网络链路不仅具有一般无线链路数据传输中遇到的延迟大、误码率高等共性问题，而且具有移动通信系统采用蜂窝频率复用方式带来的小区切换， 以及由于通信中链路性能随着地理位置变换而变化造成的GPRS网络中不可避免的经常性遭遇的冗长时延和突变时延。 这使得目前GPRS网络中使用的传统TCP或UDP传输协议均不能适应GPRS自身的链路特性，也不能实现高效的分组传输。-This paper mainly studied the W-WAN in the GPRS network for mobile video transmission problems. The article discusses the GPRS network architecture, protocol architecture, as well as link characteristics, from which we can see: GPRS network link not only has the general wireless link data transmission delay encountered in large, common problems of higher bit error rate, and with mobile communications system uses a cellular frequency reuse methods brought about by cell switching, as well as the communication link performance with the location change and change is inevitable GPRS network, the recurrent encountered lengthy delay and delay mutation. This makes the current GPRS network using the traditional TCP or UDP transport protocol are una
