Utilizing CSI to Improve Distance Estimation Precision in the Indoor Environment

چکیده
To localize mobile devices in the indoor environment, it is considered as a natural approach to make use of a commodity device. One popular work utilizes the physical layer information of WLAN devices. The information includes a beneficial characteristic, that is, the possibility of eliminating some degree of multipath fading effects. This paper deals with some experiments to improve the indoor distance estimation precision by taking advantage of the new RF channel property, CSI(Channel Status Information). It mainly aims to show how much the multipath effect can be mitigated with CSI rather than RSSI, then how it influences to the distance estimation.

Improved Channel Estimation for DVB-T2 Systems by Utilizing Side Information on OFDM Sparse Channel Estimation
The second generation of digital video broadcasting (DVB-T2) standard utilizes orthogonal frequency division multiplexing (OFDM) system to reduce and to compensate the channel effects by utilizing its estimation. Since wireless channels are inherently sparse, it is possible to utilize sparse representation (SR) methods to estimate the channel. In addition to sparsity feature of the channel, the...
