Abstract

Hovering on the task regions is an important flight state of UAV(Unmanned Aerial Vehicle). Traditional RS-turbo system needs RS and Turbo decoders, and this makes the decoder design too complex to be applied in transmission of hovering UAV's location information. In this paper, a measurement and control algorithm of hovering UAV based on improved Turbo code is proposed. The row and column of information are respectively coded and checked, and a soft-input soft-output MAP decoder is adopted. Computer simulation shows that, compared with the traditional algorithm, this algorithm could ensure that the iteration number be reduced to 1/2 when the decoding BER(bit error rate) reaches error floor, and the BER performance can quickly reach 10^-4 order at low SNR, giving 2-3 dB performance improvement. In addition, it can be implemented easily in engineering.
