中文摘要: 为了有效分析跳频信号并估计其参数, 引入一种短时傅里叶变换的快速算法, 为改善其时频聚集性, 将该算法推广到重排域。该算法降低了参数估计的算法复杂度。最后,在跳频系统中对该算法的性能进行了仿真与分析。
Abstract:To make an analysis and estimate the parameters of frequency-hopping signal, a fast algorithm to realize short time fourier transform is introduced. In order to improve the time-frequency concentration, the proposed algorithm is extended with the method known as time-frequency reassignment. The algorithm reduces complexity of parameter estimation. Finally, the algorithm performance is simulated and analyzed.
