Abstract
This paper first analyzes the existing problems of public communication network and private mobile communication network in the process of forest fire fighting; Using dynamic spectrum sharing technology, Utilizing unused and underused spectral regions to enhance the cognitive radio transmission channel capacity, The feasibility of emergency communication in the process of forest fire fighting is analyzed. Then based on the analysis and previous research results of the SD-SMSE framework, analytical expressions of overlay, Underlay and hybrid overlay/underlay waveforms are proposed; And channel capacities are analyzed respectively.The results show that adopt hybrid overlay/underlay spectrum sharing technology, To utilize both unused and underused spectral regions, To maximize channel capacity, To improve spectrum utilization, To achieve emergency communication purposes in the process of forest fire fighting.关键词
