摘要： Linear predictive speech coding system with classification of frames and a hybrid coder using both waveform coding and parametric coding for different classes of frames. Phase alignment for a parametric coder aligns synthesized speech frames with adjacent waveform coder synthesized frames. Zero phase alignment of speech prior to waveform coding aligns synthesized speech frames of a waveform coder with frames synthesized with a parametric coder. Inter-frame interpolation of LP coefficients suppresses artifacts in resultant synthesized speech frames.

摘要： A process (111,101) of sending packets of real-time information at a sender (311) includes steps of initially generating at the sender the packets of real-time information with a source rate (s11) greater than zero kilobits per second, and a time or path or combined time/path diversity rate (d11), the amount of diversity (d11) initially being at least zero kilobits per second. The process sends the packets, thereby resulting in a quality of service QoS, and optionally obtains at the sender (311) a measure of the QoS. Rate/diversity adaptation decision may be performed at receiver (361′) instead. Another step compares the QoS with a threshold of acceptability (Th1), and when the QoS is on an unacceptable side of said threshold (Th1) increases the diversity rate (d11 to d22) and sends not only additional ones of the packets of real-time information but also sends diversity packets at the diversity rate as increased (d22). Increasing the diversity rate (d11 to d22) while either reducing or keeping unchanged the overall transmission rate (sij+dij) is an important new improvement in even solely-time-diversity embodiments. In another form of the invention a single-chip integrated circuit includes a processor circuit (1511), and a rate-and-diversity control (1561). Here again, the diversity is contemplated to be time diversity, path diversity, and combined time/path diversity in various embodiments. Other embodiments disclosed encompass other processes, improved packets and packet ensembles, integrated circuits, chipsets, computer add-in cards, information storage articles, systems, computers, gateways, routers, cellular telephone handsets, wireless base stations, appliances, and packet networks, and other forms as claimed.
摘要翻译：在发送器（311）发送实时信息分组的过程（111,101）包括以下步骤：首先在发送器处产生具有大于零千比特/秒的源速率（s11）的实时信息分组，以及时间或路径或组合时间/路径分集速率（d11），分集量（d11）最初至少为零千比特每秒。该过程发送分组，从而导致服务质量QoS，并且可选地在发送方（311）获得QoS的度量。可以在接收机（361'）处执行速率/分集适配决定。另一步骤将QoS与可接受性阈值（Th1）进行比较，并且当QoS处于所述阈值（Th1）的不可接受侧时，增加分集速率（d11至d22），并且不仅发送实时时间信息，但也以多样化速率发送分集数据包（d22）。在降低或保持整体传输速率（sij + dij）的同时，增加分集率（d11至d22）是即使单时间多样性实施例中的重要新进展。在本发明的另一种形式中，单片集成电路包括处理器电路（1511）和速率分集控制（1561）。再次，在各种实施例中，分集被认为是时间分集，路径分集和组合的时间/路径分集。所公开的其他实施例包括其他过程，改进的分组和分组集合，集成电路，芯片组，计算机附加卡，信息存储产品，系统，计算机，网关，路由器，蜂窝电话手机，无线基站，设备和分组网络，和所要求的其他形式。

Increasing the diversity rate while either reducing or maintaining the overall transmission rate is new. CELP-based multiple-description data partitioning sends the base or important information plus a subset of fixed excitation in one packet and sends the base or important information plus the complementary subset of fixed excitation in another packet. Reconstruction produces acceptable quality when only one of the two packets is received and better quality when both packets are received. Reconstruction provides for single and multiple lost packets.
