matlab例程 This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel.
This an adaptive receiver for a direct-sequence spread spectrum (DS-SS) system over an AWGN channel. The adaptive receiver block is modified from the LMS adaptive filter block in DSP Blockset. For DS-SS signal reception, the adaptive filter needs to have multi-rate operation. The input sample rate i ...

It is more than a decade since GSM was first commercially available. After some unexpected delay, it
seems that finally UMTS is here to stay as a 3G system standardised by 3GPP, at least for another ten
years. UMTS will enable multi-service, multi-rate and flexible IP native-based mobile technologie ...

For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-s ...
技术资料 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. & ...
