摘要:
A method of establishing a multipath in a heterogeneous interface environment among wireless nodes including a source node, a relay node, and a destination node which receives a message from the source node via the relay node, the method including: receiving a route request message by a wireless node; and associating at least two heterogeneous interfaces of the wireless node by using a destination node address in the route request message.
摘要:
Provided is a constellation rotation relay system and constellation rotation relay method which can acquire full diversity gain by performing constellation rotation for a channel matrix in a relay network when configuring a virtual MIMO channel. The constellation rotation system includes a matrix creator for creating a symbol matrix by configuring a symbol transmitted in parallel from a source of a relay network; and a constellation rotation unit constellation rotating the symbol in the symbol matrix by adding a constellation rotation matrix to the created symbol matrix.

A method and system of relaying data are provided. The data is encoded into a turbo codeword by using a convolutional turbo code, and the turbo codeword is transmitted from a source to a relay and a destination by first puncturing the turbo codeword. The first punctured turbo codeword which is received in the relay is decoded and the decoded turbo codeword is transmitted from the relay to the destination by second puncturing the decoded turbo codeword. The turbo codeword received from the source and the relay to the destination are totaled respectively as a single turbo codeword and the totaled single turbo codeword is decoded and the data is recovered.
摘要:
A method and system for performing re-association in a WLAN mesh network are provided. A mobile node transmits authentication request information to an old node via a new node along with a mesh re-association request message for re-association of the mesh network. Upon receiving the mesh re-association request message, the old node performs re-association and authentication according to the mesh re-association request message, and transmits a mesh re-association reply message to the mobile node via the new node.

A method and system of relaying data are provided. The data is encoded into a turbo codeword by using a convolutional turbo code encoder, and the turbo codeword is transmitted from a source to a relay and a destination after puncturing by a first puncturing operation. The first punctured turbo codeword which is received in the relay is de-punctured and regenerated in a decoding operation and the regenerated turbo codeword is transmitted from the relay to the destination in punctured form after puncturing by a second puncturing operation. The punctured turbo codewords received from the source and the relay by the destination are totaled together as a totaled single turbo codeword and the totaled single turbo codeword is completely decoded to recover the data.

A biosensor for detecting an influenza A virus in a sample is disclosed, which includes: an influenza A virus antibody immobilized on a surface of Au—Fe3O4 composite; where the antibody binds with the influenza A virus in the sample, which converts 4-methylumbelliferyl-N-acetyl-α-D-neuraminic acid (MUNANA) to 4-methylumbelliferone (4-MU), where the 4-MU emits green light at pH of 5.5-6.5; and wherein the 4-MU emits blue light at pH of 9.3-11.3. In the biosensor, 1,1′-oxalyldiimidazole chemiluminescence (ODI-CL) reagent may be utilized to emit the blue and green lights.
