Radio-over-Fibre Technology for Broadband Wireless Communication Systems -The research in this thesis focussed on the feasibility of using both single-mode and multimode fibres to distribute high-frequency microwave signals to simplified remote

基于stm32的数字化语音存储与回放系统的软件设计。该系统经过拾音器采集语音信号，经带通滤波与AGC后，进入AD，然后数据存入SRAM，再由DA送至带通滤波，由喇叭将语音信号恢复。该系统可以很好的存储与回放语音信号。， 本源码是在mdk上开发的。 软件设计分两个模块：压缩解压编码与存储模块。压缩编码有PCM编码和ADPCM编码两种可用按键选择；存储是FSMC存储（256k flash）存储。-Stm32 of digital voice storage and playback system
