When I first studied Kalman filtering, I saw many advanced signal processing submissions here at the MATLAB Central File exchange, but I didn t see a heavily commented, basic Kalman filter present to allow someone new to Kalman filters to learn about creating them. So, a year later, I ve written a v ...
系统设计方案 摘要:报适了一种直接序列软扩频调制解调器的SAw实现方案
摘要:报适了一种直接序列软扩频调制解调器的SAw实现方案，并给出了相应的实验结果。该方案刘一提高系统抗干扰能力、频宽利川等方而均具有与其他技术不同的特点。同时，该技术方案为进一步研究DS-0FDM下了基石出。
学术论文 中频数字相关解扩器研究与工程实现
本文从工程设计和应用出发,根据某机载设备直接序列扩频(DS-SS)接收机声表面波可编程抽头延迟线(SAW.P.TDL)中频相关解扩电路的指标要求,提出了基于FPGA器件的中频数字相关解扩器的替代设计方案,通过理论分析、软件仿真、数学计算、电路设计等方法和手段,研制出了满足使用环境要求的工程化的中频数字相关器,经过主要性能参数 ...
无线通信 基于零中频的声表面波射频识别收发机的设计
结合声表面波（SAW）标签的物理特性以及零中频的灵活性，设计了一种双通道的声表面波射频识别系统。详细介绍了系统硬件结构，同时给出了零中频结构中直流偏置、本振泄漏、偶次失真和闪烁噪声等问题的解决方案。测试结果表明，该系统不仅成本较低，而且与同类产品相比具有更高的性价比。 ...
书籍 The Cognitive Early Warning Predictive System
I saw the light of the future when I first read Ray Kurzweil’s best-seller book The
Singularity Is Near: When Humans Transcend Biology. One cubic inch of nanotube cir-
cuitry, once fully developed, would be up to one hundred million times more powerful
than the human brain.
书籍 Interference+Mitigation+Techniques
This research work aims at eliminating the off-chip RF SAW filters from fre-
quency division duplexed (FDD) receivers. In the first approach, a monolithic passive
RF filter was constructed using on-chip capacitors and bondwire inductors. The bond-
wire characteristics were studied in details and the ...
书籍 LTE-Advanced Air Interface Technology
During the 400 days and nights before we finalized this book on January 1, 2012,
we saw the sunset decorated by the raindrop, and were accompanied by the flowers
blooming to withering. All those past memories are engraved on our hearts and will
last eternally, cementing the most profound friendship ...
