    摘要: There are provided a search method of a fixed codebook, and more particularly, a focused search method and apparatus thereof, for being applied to a speech codec for Voice over Internet Protocol (VoIP). The focused search method of the fixed codebook includes: calculating absolute values of correlation vectors of respective pulse locations of tracks 0, 1, 2, and 3 and arranging the pulse locations in a descending order of the absolute values; and selecting a predetermined number of pulse locations for each track among candidate pulse locations arranged and conducting focused search of the selected result. Therefore, it is possible to significantly reduce a calculation amount required for fixed codebook search while maintaining tone quality in a similar level.

The method is used in a code excited linear prediction (CELP) speech codec, and includes searching for a fixed codebook using a full search method that searches for the fixed codebook at all pulse positions; selecting a fixed codebook searching method by counting the number of users who are accessing a gateway, comparing the number of users with a predetermined threshold, and selecting a proper fixed codebook searching method based on the result of comparison; searching for the fixed codebook using the selected fixed codebook searching method; and checking whether the search for the fixed codebook is complete for all tracks of the CELP speech codec, terminating a routine of searching for the fixed codebook when it is determined the search is complete for all the tracks, and selecting a fixed codebook searching method again in consideration of the number of gateway users when there remains a track to be searched for. Accordingly, a fixed codebook searching method is selected in consideration of the number of users who are accessing a gateway, thereby enabling an effective adjustment of either the quality of sound or the channel capacity of the gateway.

    摘要: Provided is a method for setting a security channel between an OLT and at least one ONU in an EPON. In detail, a channel is generated by which the OLT makes a reciprocal security capability agreement with the ONU that wants to set a security channel in a discovery interval and then automatically registers the ONU with the security capability agreement. The security channel is set by which the OLT distributes an encryption key for the security with the ONU completed with the security capability agreement. A renewal point of the encryption key is shared by transmitting a message indicative of a time to change the encryption key between the OLT and the ONU both completed with the encryption key distribution.
