- The major evolution of UMTS (Universal Mobile Telecommunications System) in recent years is the High Speed Downlink Packet Access (HSDPA)which provides data rates up to 10Mbps. The implementation of HSDPA includes multicodes transmission in joint
Wireless-multimedia-sensor-networks
- 本文着重研究网络中使用的MAC协议对语音传输过程的影响，以及无线传 感器网络中适用的语音编码算法。本文首先综述了现有无线传感器网络中常用 的MAC协议，对这些协议进行了分析比较。提出了一种新的基于TDMA的MAC 协议VR-TDMA，为了测试提出的协议性能，在NS2仿真平台上对该协议进行 了仿真，结果证明该协议具有良好的实时性能。然后研究了几种常用语音编码 算法的性能，通过比较研究，认为ADPCM语音编码算法的性能符合无线传感 器网络应用的要求，并对该算法进行了简化，减少
