摘要： The present invention separates inputted triple play IP data into Internet and TV data and voice (VoIP) data, encodes the Internet and TV data permitting a long delay time according to the existing DVB-S2 standard, and encodes the voice data permitting only a short delay time according to a DVB-RCS+M standard based 4K mode. Each encoded data is subjected to the orthogonal modulation and the orthogonally modulated voice data is subjected to a direct sequence spectrum spread according to a spreading factor. The spread spectrum signal is multiplexed in a SCPC frequency division multiple access (FDMA) scheme so as to overlap with frequencies allocated to each user.

摘要： A method of routing a wireless network is provided. The method is performed by each of a group of nodes and includes: receiving a routing request signal; determining whether a node itself is a destination node, by referring to a traffic distribution table showing traffic throughput of the group of nodes and an intermediate-node weight table showing weights of intermediate nodes on all paths between the group of nodes and a source node, wherein a route path is selected by referring to the weights of intermediate nodes; and when it is determined that the node itself is the destination node transmitting a routing response signal to the source node that has transmitted the routing request signal, and receiving a packet from the source node, wherein the transmitting and receiving are performed by the determined destination node. By using the method, traffic in wireless network extreme communications can be distributed at intermediate nodes as well as at destination nodes. Therefore, all the networks can be effectively used in extreme circumstances.
