Abstract:
The adaptive power control with multi-bit quantizer of Code Division Multiple Access (CDMA) systems for communications between multiple Unmanned Aerial Vehicles (UAVs) with a link-budget based Signal-to-Interference Ratio(SIR) estimate which has distance information is applied to three inner loop power control algorithms. The speed estimation performance of these algorithms with their consecutive Transmit-Power-Control (TPC) ratios are compared to each other, and it is concluded that the speed can be estimated and shows full linearity with the TPC ratio information of Consecutive TPC Ratio Step-size Closed Loop Power Control(CS-CLPC) and Fixed Step-size Power Control (FSPC).
