NQOS
- VoIP(voice over IP) 就是通过IP 网络承载语音业务,也称IP 网络电话。当网络出现拥塞或传输差错时,语音包就会产生时延、抖动甚至丢失,导致语音不连续或中断,-VoIP (voice over IP) through the IP network to carry voice traffic. also known as IP telephone network. When the network is expected to congestion or transmissio
iad132e
- IAD (Integrated Access Device )132E(T) 综合接入设备(下文简称IAD132E(T) )是华为技术有限公司下一代网络NGN(Next Generation Network )解决方案中的重要部件,用以向公司等用户提供小容量VoIP (Voice over IP)/FoIP(Fax over IP )解决方案。IAD132E(T) 作为VoIP/FoIP 媒体接入网关,应用于NGN 用户接入层,完成模拟话音信号与IP 包之间的转换,并通过包交换网络传送数据的功能
speex-1.0.5
- 基于Speex的音频压缩和解码器的源代码,不次于iLBC,处理丢包&窄带宽时,5~30k下声音非常不错-based on the Speex audio compression and decoding of the source code, of which iLBC. handle packet loss & narrow bandwidth, 5 - 30k under very good voice

- iLBC 产生背景 在VoIP的应用中,大部分厂商采用CELP (Code Excited Linear Prediction) 算法的低速率语音编解码,如ITU G.729和G.723.1等。而VoIP应用主要在包交换的IP网络上进行传输,无法避免IP网络的丢包、延时、抖动等实时传输问题,而传统的这几个CELP算法对高丢包的处理不是很好,因而很大程度上会影响语音通话效果。 -iLBC background in the application of VoIP, Most manu
