| 摘 要： | 针对中国超宽带的4.2~4.8 GHz频段干扰抑制问题,采用组合高斯高阶导脉冲作为超宽带(UWB)原始脉冲,设计了直接序列扩频-载波调制算法,提出一种UWB频率自适应检测避让实现方案. 仿真结果表明,该方案满足中国UWB频率规划,保证了稳定的UWB正常发射功率,具有较高的传输效率,能够有效解决4.2~4.8 GHz频段检测避让(DAA)的问题.

| Abstract: | An ultra-wideband(UWB) frequency adaptive detect and avoid design method based on direct sequence spread spectrum-carrier modulation is proposed for 4.2~4.8 GHz frequency band interference suppression in China. Furthermore, the composite Gaussian n-th derivative pulse is considered as UWB original pulse. Simulation results show that the proposed DAA method can meet with the China UWB spectral mask, provide the stable UWB normal transmit power and have high transmission efficiency. |
