摘要： The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a 4th generation (4G) communication system such as long-term evolution (LTE). The present disclosure relates to beam management in a wireless communication system, and an operation method of a base station may comprise the steps of: transmitting first type reference signals; receiving feedback information on the first type reference signals; transmitting information on resources for second type reference signals, which are allocated on the basis of the feedback information, to at least one terminal; and transmitting the second type reference signals through the resources, wherein the second type reference signals are transmitted using fixed transmission beams by the base station. The present research has been conducted with the support of the “cross-departmental giga KOREA project” of the government (the ministry of science and ICT) in 2017 (No. GK17N0100, Development for mmWave-based 5G mobile communication system).

摘要： An apparatus and method for concealing frame erasure and a voice decoding apparatus and method using the same. The frame erasure concealment apparatus includes: a parameter extraction unit determining whether there is an erased frame in a voice packet, and extracting an excitement signal parameter and a line spectrum pair parameter of a previous good frame; and an erasure frame concealment unit, if there is an erased frame, restoring the excitement signal and line spectrum pair parameter of the erased frame by using a regression analysis from the excitement signal and line spectrum pair parameter of the previous good frame. According to the method and apparatus, by predicting and restoring the parameter of the erased frame through the regression analysis, the quality of the restored voice signal can be enhanced and the algorithm can be simplified.

摘要： A method and apparatus to search a codebook including pulses that model a predetermined component of a speech signal. The method includes the operations of selecting a predetermined number of paths corresponding to a predetermined number of pulse locations that are most consistent with the predetermined component, from among paths corresponding to pulse locations of a predetermined pulse location set allocated to at least one branch that connects one state of a predetermined Trellis structure to another state, performing the path selecting operation on each of states other than the one state, and selecting a path corresponding to pulse locations that are most consistent with the predetermined component, from among paths including the selected paths. Accordingly, the number of calculations required during a codebook search is reduced.
