New Fast Algorithm for Modulated Complex Lapped Transform With Sine Windowing Function

A novel algorithm for fast computation of the modulated complex lapped transform (MCLT) with sine windowing function is presented. For the MCLT of length-2
M
input data sequence, the proposed algorithm is based on computing a length-2
M
type-II generalized discrete Hartley transform. Comparison with existing algorithms shows that the proposed method achieves the minimal number of arithmetic operations.
