    Abstract: Systems and methods for transmitting and receiving OFDM symbols are provided which enable the otherwise wasted transmission time normally used as a prefix for each OFDM symbol to contain useful information. At the receiver, the received signal is processed to convert received OFDM symbols from a linear convolution with the channel to a cyclic convolution.

    Abstract: In a wireless multi-hop relay network arranged in a tree topology, the base station and one or more relay stations are associated as a virtual base station (VBS). The base station and each relay station have a unique virtual base station identifier (VBS-ID) associated with the path defined by the base station and the one or more relay stations. A relay station in the branch uses its VBS-ID for communicating with an attached subscriber station (e.g. a mobile station) such that communications between the base station and subscriber station occur via the VBS. Subscriber station data communications are relayed between the base station and the one or more relay stations over the VBS via a tunnel connection. The VBS is auto configurable. Mobility for subscriber stations and 10 relay stations is provided through reconfiguration of VBS's.

    Abstract: The present invention provides a method for generating routing paths in a multi-hop network. The multi-hop network includes a base station, at least one relay station, and at least one non-relay mobile station. The routing paths are paths between the base station and the at least one non-relay mobile station via the at least one relay station. The base station broadcasts a path discovery message (PDM) including a path list with a starting point of the path list being the base station. Each of the relay stations receives the PDM and updates the PDM by adding their own respective node identifier to the path list and broadcasting the updated PDM. The PDMs eventually reach the non-relay mobile station. The non-relay mobile stations reply to the base station by sending the base station the updated path list between the base station and the non-relay mobile station. In some embodiments the base station or the at least one non-relay mobile station acting as a source node sends a dynamic service (DSx) message including an end-to-end path list to an end of path destination. The relay stations use the path list to forward the message between the source node and the end of path destination. In some implementations the multi-hop network operates in a manner that is consistent with any one of: IEEE 802.16, IEEE 802.16d, and IEEE 802.16e.

    Abstract translation: 本发明提供了一种在多跳网络中生成路由路径的方法。 多跳网络包括基站，至少一个中继站和至少一个非中继移动站。 所述路由路径是经由所述至少一个中继站的所述基站与所述至少一个非中继移动站之间的路径。 基站广播路径发现消息（PDM），其包括具有作为基站的路径列表的起始点的路径列表。 每个中继站接收PDM，并通过将其各自的节点标识符添加到路径列表并且广播更新的PDM来更新PDM。 PDM最终到达非中继移动台。 非中继移动台通过在基站和非中继移动台之间发送基站更新的路由列表来回复基站。 在一些实施例中，用作源节点的基站或至少一个非中继移动台将包括端到端路径列表的动态服务（DSx）消息发送到路径目的地的末端。 中继站使用路径列表在源节点和路径目的地的末尾之间转发消息。 在一些实现中，多跳网络以与IEEE 802.16，IEEE 802.16d和IEEE 802.16e中的任何一个相一致的方式运行。

    Abstract: An adaptable orthogonal frequency-division multiplexing system (OFDM) that uses a multiple input multiple output (MIMO) to having OFDM signals transmitted either in accordance with time diversity to reducing signal fading or in accordance with spatial diversity to increase the data rate. Sub-carriers are classified for spatial diversity transmission or for time diversity transmission based on the result of a comparison between threshold values and at least one of three criteria. The criteria includes a calculation of a smallest eigen value of a frequency channel response matrix and a smallest element of a diagonal of the matrix and a ratio of the largest and smallest eigen values of the matrix.
