多频带干扰对超宽带调制技术性能的影响分析

研究了多频带干扰对超宽带调制技术性能的影响。在高斯脉冲波形的条件下，推导得出了超宽带调制技术抗多频带干扰能力指标的数学表达式。在多频带干扰下，分别对超宽带调制技术、直接序列扩频调制技术和跳频调制技术进行了抗干扰性能比较分析和性能仿真。分析和仿真结果表明，在大多数的情况下，超宽带调制技术抗多个频带干扰的能力明显优于直接序列扩频调制技术和跳频调制技术。

Performance of Ultra - Wideband Communication in the Presence of Multi - Band Interference

The influence of multi-band interference on ultra-wideband (UWB) communication is analyzed in this paper. The closed form of the JR expression is derived based on the Gaussian pulse waveform. The direct sequence spread spectrum communication (DS - SS) and frequency hoping spread spectrum communication (FH - SS) are respectively compared with UWB communication in performance and analyzed in the presence of multi-band interference. According to common variable of the above three communication models, the JR performance curves can be simulated respectively. A comparison based on JR parameter between the multi-band interference suppression capabilities of above three communication models is carried out, which shows that in most cases, the multi-band interference suppression of UWB is superior to that of DS - SS and FH - SS.
