    • A file system can be provided in a capture system to efficiently read and write captured objects. In one embodiment, such a file system includes a plurality of queues to queue captured objects to be written to a disk, each queue being associated with one of a plurality of object types, and each queue containing captured objects of the type associated with each queue. A scheduler can be provided to select one of the plurality of queues, and a block manager to select a partition of a disk, the partition being associated with the object type of the captured objects in the selected queue. A disk controller configured to write contiguous blocks of data from the selected queue to the selected partition is connected to the block manager to enable writing to a disk.

    • Two network nodes may exchange messages through a relay using physical-layer network coding combined with forward error correction coding (FEC). The relay determines a prime field order based on the channel condition and communicates the field order to the network nodes. Each network node encodes an outgoing message with linear codes over a field such as finite field of the field order, and transmits a signal carrying the encoded outgoing message. The relay receives a composite signal carrying the summation of the messages from the two network nodes. The relay decodes the composite signal and extracts a composite message with linear codes over finite field of field order, and broadcasts a signal carrying the composite message. Each network node receives the signal from the relay and extracts the message intended for it using linear subtraction over finite field of field order.
    • 两个网络节点可以使用结合前向纠错编码(FEC)的物理层网络编码通过中继交换消息。 继电器基于信道条件确定主场顺序,并将该场顺序传送到网络节点。 每个网络节点通过诸如场顺序的有限域的字段编码具有线性码的输出消息,并且发送携带编码的输出消息的信号。 继电器接收携带来自两个网络节点的消息总和的复合信号。 中继解码复合信号,并通过有限场场顺序提取具有线性码的复合消息,并广播携带复合消息的信号。 每个网络节点接收来自中继器的信号,并通过有限场域顺序使用线性减法提取预期的消息。

    • A two-way relay wireless communication method and device may combine multiple bit steams, for one source node and two target nodes, and broadcasting a network coded combined bit sequence to reduce the number of time slots for transmission. A first device may receive a signal from the source node and a target node simultaneously in a time slot. The first device may receive subsequent signals from the source node and multiple target nodes simultaneously in successive time slots. Hierarchical modulation may be applied to the received signals. The first device may decode the received signals and generate a plurality of intermediate bit sequences (IBS)s for a broadcast transmission. The generated IBSs may be grouped according to a channel condition. A second device may be configured to receive the broadcast transmission and decode a portion of the broadcast transmission that is intended for the second device.
