Abstract : We present in this letter an efficient direct method for the computation of a length-N type-II generalized discrete Hartley transform (GDHT) when given two adjacent length-N/2 GDHT coefficients. The computational complexity of the proposed method is lower than that of the traditional approach for length N ≥ 8. The arithmetic operations can be saved from 16% to 24% for N varying from 16 to 64. Furthermore, the new approach can be easily implemented.
