AREA-BASED SNOW DAMAGE CLASSIFICATION OF FOREST CANOPIES USING BI- TEMPORAL LIDAR DATA
Change detection airborne laser scanning logistic regression
2014/6/5
Multitemporal LiDAR data provide means for mapping structural changes in forest canopies. We demonstrate the use of area-based estimation method for snow damage assessment. Change features of bi-tempo...
使用LDC码的BI-STCM-ID系统中的星座映射分析
空时编码调制 星座映射 LDC码
2009/7/10
研究了BI-STCM-ID系统中的星座映射问题。证明了在使用LDC（Linear Dispersion Code）空时编码方案的BI-STCM-ID系统中，基于最大化编码增益的高维星座映射设计优化问题等价于基于最大化欧式距调和均值的一维星座映射设计优化问题。
