BCS
- 压缩传感是一个从2006年左右开始兴起的研究领域，它关注于如何采样信号，也就是信号的采样方式或者压缩方式。通过设计一种特殊的采样方案，可以使得采样频率降低为信号的“信息率”，而不是传统的奈奎斯特采样率，于是，实际的采样率可以大大低于奈奎斯特频率，却只损失很少的信息量，依然保持了充足的信息量足以恢复出采样前的原始信号。这个研究思想挑战了奈奎斯特频率的理论极限，会对整个信号处理领域产生极其深远的影响，同时，信号处理的许多应用领域也会随之发生根本性的发展和变化。 -Compressive sens
3.5GHz--channel-measurements
- 在3.49-3.51GHZ频段内的典型中国城市环境下，地面信号衰落仍服从经典的指数对数分布。在中度误差（σx =10.291）下，路损指数在3.1-3.7之间。半径2公里的小区内，RMS时延在3-4微秒之间；典型的办公室环境中，存在直达径时RMS时延小于0.1微秒。在城市环境中，多径现象很明显，主要由高层建筑物引起，并以簇的方式存在。在城市中低速移动条件下（接收机移动速度小于100 Km/h）某一强径的生存时间通常超过10分钟，但相对到达时间会发生滑动。单一小区内的传播环境具有一定相关性，如果存
