A method includes obtaining at least a portion of an audio stream containing speech activity. At least the portion of the audio stream includes multiple segments. The method also includes, for each of the segments, generating an embedding vector that represents the segment. The method further includes, within each of multiple local windows, clustering the embedding vectors into one or more clusters to perform speaker identification. Different clusters correspond to different speakers. The method also includes presenting at least one first sequence of speaker identities based on the speaker identification for the local windows. The method further includes, within each of multiple global windows, clustering the embedding vectors into one or more clusters to perform speaker identification. Each global window includes two or more of the local windows. The method further includes presenting at least one second sequence of speaker identities based on the speaker identification for the global windows.

The present invention relates to a method and apparatus for estimating a channel in a mobile communication network. In particular, the present invention relates to a method of estimating a channel under a channel environment where interference between neighboring base stations exists in a mobile communication network using an orthogonal frequency division multiplexing (OFDM) method. In order to estimate a channel, one cluster is divided into two sub-clusters, and pilot sub-carrier signals included in at least one sub-cluster in an OFDM symbol direction are used. Therefore, it is possible to further improve performance as compared to a method of estimating a channel by using pilot sub-carriers included in one cluster.

An apparatus and method for booting a NAND flash memory of a mobile terminal. The apparatus comprises a NAND flash memory, a synchronous dynamic random access memory (SDRAM), a main read only memory (ROM), a main control unit, and a sub-control unit. The NAND flash memory stores an application code necessary for execution of an additional function provided in the mobile terminal, and a secondary program loader (SPL) boot code for access to the application code. The SDRAM stores the SPL boot code and application code sent from the NAND flash memory. The main ROM stores code values for the booting of the NAND flash memory and an initial program loader (IPL) boot code for initial access to the NAND flash memory. The main control unit detects and outputs the IPL boot code from the main ROM in response to a reset signal inputted thereto and then outputs the reset signal. The sub-control unit receives the IPL boot code and reset signal output from the main control unit, drives the received IPL boot code in response to the received reset signal to access the NAND flash memory and receive the SPL boot code therefrom, stores the received SPL boot code in the SDRAM, drives the SPL boot code stored in the SDRAM to access the NAND flash memory and receive the application code therefrom, stores the received application code in the SDRAM, and completes the booting of the NAND flash memory by driving the application code stored in the SDRAM.
