摘要:
为有效解决跳频通信系统中的参数估计问题,本文对基于时频分析的跳频参数估计算法——时频矩法做出改进。引入了门限来处理时频矩图像,抑制了噪声对算法的干扰。为进一步提高跳频参数估计性能,将改进的时频矩法与时频图修正算法结合。仿真结果表明,经过修正之后,时频图更清晰,估计跳频参数的误差更小。
Abstract:
In order to effectively solve the parameter estimation problem in the frequency hopping communication system, this paper improves the time-frequency moment method—frequency hopping parameter estimation algorithm based on time-frequency analysis. A threshold is introduced to process the time-frequency moment image, which suppresses the interference of noise to the algorithm. To further improve the performance of frequency hopping parameter estimation, the improved time-frequency moment method is combined with the time-frequency diagram correction algorithm. The simulation results show that the time-frequency diagram is clearer and the error of the estimated frequency hopping parameters is smaller after the correction.
