Based on CSI, we are able to capture both of amplitude and phase information in indoor positioning scene. We are interested in the improvement on original RSS-fingerprint-based localization problems. <br /> <br /> Another problem in current WiFi-based approaches is that when more targets exists in the room, the data size required for training data of multiple targets would be exponential large. By using probabilistic methods, we hope to infer multiple targets with the training model of single person. GMM, CRF are used to solve such problem.<br /> <br /> == 主要方法 ==<br /> * 基于CRF图模型进行多人位置推断<br /> * 以多普勒频移的运动方向感知辅助的多人定位<br /> <br /> = 参与人员 =<br /> 申晗<br /> 马文硕<br /> <br /> = 相关资料 =<br /> * 对CSI相关性质的分析 {{#l:week2.pptx}}<br /> * 基于KNN与Naive Bayes的定位实验{{#l:Localization_alg.pdf}}<br /> * 室内定位方法Review {{#l:review.pdf}}<br /> <br /> = 项目进展 =<br /> == 2015年3月1日 ==<br /> 文献调研-CSI，定位相关<br /> == 2015年4月20日 ==<br /> 完成基于KNN和Naive Bayes方法的定位<br /> == 2015年6月10日 ==<br /> 确认实验方向为基于WIFI的多人定位<br /> == 2015年7月1日 ==<br /> 尝试使用基于CRF方法的多人位置推断<br /> <br /> <br /> = 相关链接 =</div>
