目前2.4kbps的混合激励线性预测 (MELP) 语音编码方法已经被确定为美国新的联邦语音编码标准.本文提出了一种改进的MELP语音编码方法,利用滤波器相似度和基于LPC系数分类的矢量量化技术,可以把MELP的码率降到1.7kbps以下,仍有较好的合成语音质量.(An Improved MELP Speech Coder)

NXP LPC11xx 系列单片机IAP在线升级的研究。经过长时间的摸索，研究LPC1114 IAP在线升级，因此写下文档记录方便以后查阅，同时也给需要IAP在线升级的同仁提供参考。文档内容是实践过的，经过多次反复测试(NXP LPC11xx series MCU IAP online upgrade. LPC1114 IAP online upgrade after a long period of exploration, research, write a convenient documented after inspection, but also to the need to IAP online upgrade colleagues to provide a reference. Document content is practice, after repeated testing)

说明：  在此基础上，设计一种温度测量系统，能够检测温度，并通过按键调整温度的上下限值，若超过该限值，进行报警提示。该系统的硬件子电路主要用Protues仿真软件实现，具体的子电路包括：恒流源电路（TLC2543芯片）、信号放大调理电路（两线制铂电阻PT100）、单片机最小系统（AT89C51）、A/D转换电路、按键电路、显示电路、声光报警器等。该系统的软件电路以C语言为基础，在Keil中实现。最后通过软硬结合，实现电路的各种情况仿真，以此验证电路设计的正确性和合理性。(On this basis, a temperature measurement system is designed, which can detect the temperature and adjust the upper and lower limits of the temperature by pressing the key. If it exceeds the limit, an alarm will be given. The hardware sub circuit of the system is mainly realized by Proteus simulation software. The specific sub circuits include: constant current source circuit (TLC2543 chip), signal amplification and conditioning circuit (two-wire platinum resistance PT100), minimum system of single chip microcomputer (AT89C51), a / D conversion circuit, key circuit, display circuit, sound and light alarm, etc. The software circuit of the system is based on C language and implemented in keil. Finally, through the combination of hardware and software, the circuit simulation is realized to verify the correctness and rationality of the circuit design.)
