| Rake, as a key technique for communication, is of great significance for the receiver development accommodated to ground-to-air data link. This paper mainly deals with UAV-based rake methods using modern signal and information processing techniques.With the detailed analysis of the low-elevation model and conventional rake receiver, an investigation of the rake method is presented. A new UAV-based method of post-consolidation and post-demodulation is proposed. A further improvement is achieved in the process and reliability by using sectionalized weight and self-regulating search. On the basis of this, the simulation scheme is designed according to the actual project requirements. The simulation results illustrate the effectiveness of the new method with a good meet to the requirements of the UAV data link and promote the theory of future receiver. |
