In this paper,the 1-D real-valued discrete Gabor transform(RDGT)proposed in the previous work and its relationship with the complex-valued discrete Gabor transform(CDGT)are briefly *** time-recursive RDGT algorithms for the efficient and fast computation of the 1-D RDGT coefficients and for the fast reconstruction of the original signal from the coefficients are developed in both critical sampling and oversampling *** parallel lattice structuires for the implementation of the algorithms are *** the computational complexity analysis and comparison show that the proposed algorithms provide a more efficient and faster approach to the computation of the discrete Gabor transforms.
