    • The present invention relates to a scheduling apparatus and a method thereof in an HPi system. A scheduling algorithm is applied appropriate to a characteristic of each multimedia service (e.g., real-time service, non real-time service, best-effort service, etc.) and a transmission order of the IP packets transmitted from a network is determined such that a transmit wait queue is generated. Radio resource allocation is performed in accordance with the order of the data items queued in the transmit wait queue, the size of transmittable data is determined such that a PDU is generated. In addition, frame data formed of bursts of PDUs is generated and transmitted to a physical layer. Therefore, a scheduling algorithm can be applied appropriate to characteristics of each multimedia service. In addition, packet scheduling is performed in two steps in order to schedule traffic corresponding to radio frames such that packets can be efficiently processed.
    • 本发明涉及一种HPi系统中的调度装置及其方法。 适用于每个多媒体业务的特性(例如,实时业务,非实时业务,尽力服务等)的调度算法被确定为从网络发送的IP分组的传输顺序, 生成发送等待队列。 根据发送等待队列中排队的数据项的顺序执行无线资源分配,确定可发送数据的大小,使得生成PDU。 另外,由突发的PDU形成的帧数据被生成并发送到物理层。 因此,可以适用于每个多媒体业务的特征的调度算法。 另外,分两个步骤进行分组调度,以便调度与无线帧相对应的业务,从而可以有效地处理分组。

    • Provided are a flexible bit rate code vector generation method and a wideband vocoder employing the same. This invention implements a flexible bit rate by getting three code vectors which are composed of 24, 16, and 8 pulses, at a time in a search process, through improvement of an algebraic codebook search process in a wideband AMR-WB vocoder. The method includes the steps of: performing a preprocess, wherein the preprocess divides a sub-frame by tracks and decides a pulse position having a maximum value in each track; among a plurality of pulses to be searched, fixing a same number of pulses as the tracks to the position with the maximum value of each track sequentially, and searching optimal positions having a minimum error with a target signal by combining two pulses in two consecutive tracks for the remaining pulses; and creating a code vector with flexible bit rate.
    • 提供了一种灵活的比特率码矢量生成方法和采用该方法的宽带声码器。 本发明通过在宽带AMR-WB声码器中改进代数码本搜索处理,通过在搜索过程中一次获得由24,16和8脉冲组成的三个码向量来实现灵活的比特率。 该方法包括以下步骤:执行预处理,其中预处理通过磁道划分子帧,并确定每个磁道中具有最大值的脉冲位置; 在要搜索的多个脉冲之间,将相同数量的脉冲固定到具有每个磁道的最大值的位置,并且通过在两个连续的轨道中组合两个脉冲来搜索具有目标信号的最小误差的最佳位置 剩下的脉冲; 并创建一个具有灵活位速率的码矢量。
