Description: WB-AMR VMR-WB 是新型可变速率多模式宽带语音编解码器，专为无线 CDMA 2000标准而设计，目的在于在 50 至 7000 HZ 的频带上进行语音编码，采样率为 16 KHZ。VMR-WB 基于 3GPP AMR-WB (G722.2) 编解码器，在每秒速率12.65 Kbit 上可实现互操作。 VMR-WB 工作模式有四种，具体选择哪种应视网络的流量情况而定。前三种模式专门针对 CDMA 系统，而第四种模式为 AMR-WB 互操作性模式。 VMR-WB 与 AMR-WB 的互操作性允许 GSM/WCDMA 与 CDMA2000 系统无须进行自动解码即可通信，这就不至于增加额外的延迟以及引起语音质量下降-WB-AMR VMR-WB is a new variable-rate multimode wideband speech codec designed for wireless CDMA 2000 standard design, aimed at 50 to 7000 HZ frequency band for voice coding, sampling rate of 16 KHZ. VMR-WB based on the 3GPP AMR-WB (G722.2) codec rate of 12.65 Kbit per second can be interoperable. VMR-WB mode four, the specific choice of which network traffic should be as the case may be. The first three models specifically for the CDMA system, while the fourth mode of AMR-WB interoperable mode. VMR-WB and AMR-WB allows the interoperability of GSM/WCDMA and CDMA2000 systems can not automatically decode the communication, which without increasing the delay and the additional decline in voice quality caused by

Description: Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne, CDMA2000 (the 3G evolution of cdmaOne) and WCDMA (the 3G standard used by GSM carriers), which are often referred to as simply CDMA, and use CDMA as an underlying channel access method.

Description: This paper describes a software-radio architecture developed for providing realtime wide-band radio communication capabilities in a form attractive for advanced 3G systems research. It is currently being used to implement signaling methods and protocols similar, but not limited to, evolving 3G radio standards (e.g. UMTS, CDMA2000). An overview of the hardware system is provided along with example software implementations on both high-performance DSP systems and conventional microprocessors.
