长序列实值离散Gabor变换窗函数的快速求解算法
Fast algorithm for window computation in real-valued discrete Gabor transform for long sequences
摘要
Abstract
To reduce the high complexity of the window computation using the biorthogonal relationship between the analysis window and the synthesis window in the Real-valued Discrete Gabor Transform(RDGT)for infinite or long sequences, this paper presents a fast algorithm based on the Discrete Hartley Transform(DHT). By transforming the equa-tion set of the biorthogonal relationship into the form of DHT, the equation set can be separated into several independent sub-equation sets so that the computational complexity can be reduced. The experimental results also indicate that the pro-posed fast algorithm is correct and effective.关键词
