ETSI TS 122 076-2007 数字蜂窝通讯系统(阶段2+).通用移动通信系统(UMTS).自适应多速率编码解码器的噪声抑制.服务描述.阶段1(3GPP TS 22.076,7.0.0版本,7发行)
Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); Noise suppression for the AMR codec; Service description; Stage 1 V7.0.0; 3GPP TS 22.076 version 7.0.0 Release 7
The present document specifies the stage 1 description for the Noise Suppression feature for the AMR codec which
enhances the input speech signal corrupted by acoustic noise. In analogy with ITU-T Recommendations I.130, Stage
1 is an overall service description, from the service subscriber's and user's standpoints, that views the network as a
single entity which provides services to the user.
