RSSI(Received Signal Strength Indicator)是接收信号的强度指示,它的实现是在反向通道基带接收滤波器之后进行的。 为了获取反向信号的特征,在RSSI的具体实现中做了如下处理:在104us内进行基带IQ功率积分得到RSSI的瞬时值,即RSSI(瞬时)=sum(I^2+Q^2);然后在约1秒内对8192个RSSI的瞬时值进行平均得到RSSI的平均值,即...
一般 RSS 的强度受到三个方面影响:1)路径衰减;2)遮挡;3)多径效应。 RSSI(received signal strength indicator): 是接受信号强度指示,通过人为处理,而得到的信号强度。一般,RSS负数不太好理解,可以通过变换转化为正值。无线局域网供应商可以按照私有方式定义RSSI值,即通过某种公式将原有RSSI的区间映射为自己定义的区间...
3. 从RSSI到信道响应(FROM RSSI TO CHANNEL RESPONSE) 室内定位的主要障碍在于室内环境中的多径衰落(multipath fading)和时间动态(temporal dynamic)。RSSI 等传统的功率特征在复杂的室内环境下无法提供足够的分辨率和鲁棒性,因为RSSI是相位快速变化的多径信号(multipath signals)的叠加。近年的工作通过深入物理层并利用更...
"According to the data sheet, the pad "RSSI" in ONET8521T sends analog current signal proportional to input data amplitude. My application is extracting a low frequency signal components from this "RSSI" pad. Then, my questions are 1. what is the response time of the "RSSI" sign...
Different from RSSI, the PHY layer power feature, channel response, is able to discriminate multipath characteristics, and thus holds the potential for the convergence of accurate and pervasive indoor localization. Channel State Information (CSI, reflecting channel response in 802.11 a/g/n) has ...
