Abstract: Provided are a signal transforming method and a signal transforming device. For example, the signal transforming method includes determining a minimum-value matrix and a maximum-value matrix with respect to elements of a matrix used in frequency transformation, wherein the minimum-value matrix is configured of elements of minimum value and the maximum-value matrix is configured of elements of maximum value; determining a maximum threshold value of a result value of a function indicating at least one selected from transform distortion, normalization, and orthogonality of the matrix; determining a transform matrix configured of elements that are greater than the elements of the minimum-value matrix and less than the elements of the maximum-value matrix at respective positions of the matrix, and in which the result value of the function is less than the maximum threshold value; and transforming an input signal by using the determined transform matrix.

Abstract: An auto-accelerated method is applied to a mobile communication equipment. The mobile communication equipment includes a primary module and a secondary module with a specific communication pattern including a transmission interface. The primary module sends out an inquiry command to inquire the transmission interface corresponding to the secondary module. The secondary module sends out a reply command to answer the inquiry command. According to the reply command, the primary module turns a switch inside the primary module to reach a transmission unit corresponding to the transmission interface of the secondary module. After the switching, the data transmission is made through between the primary module and the secondary module.
