Specifying the Jitter Performance

The question of sample-clock quality is a perennial one for digital audio equipment designers. Yet most chip makers provide very little information about the jitter performance of their products. Con

基于Intel_PXA27x的AMR-WB性能优化与移植

· 摘要:  AMR-WB(Adaptive Multi-Rate Wideband Speech Codec)同时被3GPP和ITU-T选定为高品质宽带语音编码标准,在移动终端上的实际应用和针对不同DSP平台,提出了优化和移植的任务.对AMR-WB在Intel PXA27x处理器上的优化经验进行了总结.讨论的移植优化方案对于其他语音编解码的移植与优化亦有参考价值.

超宽带脉冲与MB-OFDM物理层的FPGA实现

现代通信系统对带宽和数据速率的要求越来越高,超宽带(ultra-wideband,UWB)通信以其传输速率高、空间容量大、成本低、功耗低的优点,成为解决企业、家庭、公共场所等高速因特网接入的需求与越来越拥挤的频率资源分配之间的矛盾的技术手段。 论文主要围绕两方面展开分析:一是介绍用于UWB无载波脉冲调制及直接序列码分多址调制(DS-CDMA)的新型脉冲,即Hermite正交脉冲,并且分析了这种构建
