Adaptive beam steering: RSSI performance

2015 International Conference on Computer, Communications, and Control Technology (I4CT), 2015
Adaptive beam steering antenna has been develop in this research. The proposed antenna is capable to steer the radiation pattern to phi of 0°, 45°, 135°, 225° and 315° angles and theta of 0°, 13°, 15°, 10° and 12°. This could be achieved with the suitable design antenna based on the patch yagi-uda antenna concept with a single radiator and four ...

Novel RSSI-based techniques for indoor localization

2017 IEEE Radio and Antenna Days of the Indian Ocean (RADIO), 2017
This paper considers indoor localization based onmultilateration and averaged received signal strength indicator(RSSI). We propose two approaches called three minimumdistances method (TDM) and weight values adjustment method(WAM) to deal with the poor accuracy of distances deducedfrom RSSI.

Distance estimation using RSSI and particle filter

ISA Transactions, 2015
This paper presents a particle filter algorithm for distance estimation using multiple antennas on the receiver's side and only one transmitter, where a received signal strength indicator (RSSI) of radio frequency was used. Two different placements of antennas were considered (parallel and circular).
