％ inputs:
％ sig2 - noise variance
％ Mt - number of Tx antennas
％ Mr - number of Rx antennas
％ x - vector of complex input symbols (for MIMO, this is a matrix, where each column
％ is the value of the antenna outputs at a single time instance)
％ H - frequency selective channel - represented in block-Toeplitz form for MIMO transmission
％ N - number of symbols transmitted in OFDM frame
％
％ outputs:
％ y - vector of channel outputs (matrix for MIMO again, just like x matrix)
％ create noise vector sequence (each row is a different antenna, each column is a
％ different time index) note: noise is spatially and temporally white(channel characteristics of OFDM Channel transmission simulatorChannel transmission simulator inputs: sig2- noise variance Mt- number of Tx antennas Mr- number of Rx antennas x- vector of complex input symbols (for MIMO, this is a matrix, where each column is the value of the antenna outputs at a single time instance) H- frequency selective channel- represented in block-Toeplitz form for MIMO transmission N- number of symbols transmitted in OFDM frame outputs: y- vector of channel outputs (matrix for MIMO again, just like x matrix) create noise vector sequence (each row is a different antenna, each column is a different time index) note: noise is spatially and temporally white)

phaseU
PhaseU，一种
实时LOS识别方案，既适用于静态也适用
商用WiFi基础设施的移动场景。 各种室内场景的实验结果表明了这一点
PhaseU始终优于以前的方法，实现了总体LOS和NLOS检测率为94.35％和
静态情况下为94.19％，移动电话均高于80％
上下文。 此外，PhaseU实现了实时功能
连接AP的毫秒级延迟和1秒延迟
对于未连接的AP，这远远超出现有方法(PhaseU, a
real-time LOS identification scheme that works in both static
and mobile scenarios on commodity WiFi infrastructure. Experimental results in various indoor scenarios demonstrate that
PhaseU consistently outperforms previous approaches, achieving overall LOS and NLOS detection rates of 94.35% and
94.19% in static cases and both higher than 80% in mobile
contexts. Furthermore, PhaseU achieves real-time capability with
millisecond-level delay for a connected AP and 1-second delay
for unconnected APs, which is far beyond existing approaches)
