Background technique

The data center is a complex set of facilities. It includes not only computer systems and other companion devices (such as communication and storage systems), but also redundant data communication connections, environmental control equipment, monitoring equipment, and various security devices.

In the prior art, in order to enable communication between the servers, wireless transceivers and directional antennas are placed on the machines carrying the servers, and planarized wireless signals are propagated according to the direction of propagation of the antennas.

BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

Referring to FIG. 1, an embodiment of a signal transmission node in an embodiment of the present invention includes:

Signal receiving unit 101, signal determining unit 102, signal reproducing unit 103, signal synthesizing unit 104, signal transmitting unit 105;

In a practical application, the signal transmission environment of the embodiment of the present invention includes at least three signal transmission nodes, which are respectively a source node, a target node, and an adjacent node; and the source node is a signal transmission node that sends a first signal to the destination node. The neighboring node is a signal transmission node located near the destination node, where there may be multiple neighboring nodes.

The signal receiving unit 101 is configured to receive a pending signal sent by a non-local signal transmitting node. The signal transmission node in the embodiment of the present invention can receive the signal as the target node or the neighboring node, and can also send the signal as the source node, which is not limited herein.

The signal determining unit 102 performs a signal type determination on the to-be-determined signal, where the signal type includes: a local source signal, a non-native source signal, and an interference signal; the source signal is a signal sent by the source node to the destination node, and the non- The source signal is a signal sent by the non-source node to the destination node, and the interference signal is a signal received by the non-destination node;

It can be understood that the distinction between the source signal, the non-native signal and the interference signal is only for the signal transmission node that also receives the signal, that is, the signal to be transmitted is sent to the source node of the signal. For the same kind of signal.

If the to-be-determined signal is a source signal, the signal synthesizing unit 104 synthesizes the local source signal and the non-native source signal corresponding to the local source signal to obtain a signal required by the local signal transmission node;

If the undetermined signal is a non-native signal, the signal synthesizing unit 104 synthesizes the non-native source signal and the local source signal corresponding to the non-native source signal to obtain a signal required by the local signal transmission node. If the to-be-determined signal is an interference signal, the signal regeneration unit 103 performs signal amplification on the interference signal, and then the signal transmission unit 105 transmits the interference signal amplified by the signal to the dry signal. Corresponding destination node.

In the practical application of the embodiment of the present invention, the destination node and the neighboring node receive the pending signal sent by the source node, and the pending signal is regarded as the local source signal on the destination node side, and is regarded as the interference signal on the neighboring node side. After receiving the interference signal, the neighboring node will amplify the signal, and then adjust the signal radiation angle to forward to the destination node. For the destination node, the amplified signal of the signal forwarded by the neighboring node is a non-source. a signal, and corresponding to the local source signal having the same destination node.

Therefore, if the local signal transmission node receives the local source signal and the local signal transmission node has a neighboring node, the local signal transmission node also receives the corresponding signal sent by the neighboring node and the local source signal. Similarly, if the local signal transmission node receives the non-native signal and the local signal transmission node has an adjacent node, the local signal transmission node also receives the source node. a non-native source signal corresponding to the non-native source signal.

In practical applications, since the neighbor nodes also need to be the source nodes of other signal transmission nodes, there is also a fixed signal radiation angle; when the neighbor nodes need to forward signals to the destination node, it is necessary to adjust the fixed signal radiation angle. The angle angle of the adjustment needs to be determined according to the layout of each signal transmission node; exemplarily, if the layout of each signal transmission node is a lattice-like neat and symmetrical structure, the adjustment angle may be 90 degrees, 180 degrees or 270 degrees.

In the embodiment of the present invention, the local signal transmission node not only receives the local source signal sent by the source node, but also receives the non-native source signal sent by the neighboring node, and synthesizes the two signals, so that the signal quality is better. The signal is such that, at the source node side, the transmission power of the signal can be adapted to a reduction, for example, using a wide-valve signal of a low-cost low-frequency band for signal transmission.

In the embodiment of the present invention, the signal determining unit may determine the signal type according to the signal to be determined. If the to-be-determined signal is a source signal or a non-native source signal, the signal synthesizing unit may correspond to the local source signal or the non-native source signal. The non-native source signal or the source signal performs signal synthesis to obtain a signal required by the local signal transmission node; if the pending signal is an interference signal, the signal regeneration unit performs signal amplification on the interference signal, and then The signal sending unit sends the interference signal amplified by the signal to the destination node corresponding to the interference signal; thereby effectively reducing the interference problem of the dense wireless network, and increasing the signal-to-noise ratio and bandwidth by using the interference, and also reducing the antenna Narrow lobed Claim.

In an actual application, the signal judging unit and the signal synthesizing unit may further include other modules to implement corresponding functions. Referring to FIG. 2, another embodiment of the signal transmission node in the embodiment of the present invention includes:

The signal determining unit 102 may further include: a power estimating module 1021, a channel estimating module 1022, and a signal determining module 1023;

Specifically, the power estimation module 1021 is configured to perform power check on the to-be-determined signal. The signal determining module 1023 determines, according to the result of the power check and the corresponding power threshold, whether the destination node of the to-be-determined signal is The local signal transmission node, if yes, the undetermined signal is a source signal or a non-native signal, and if not, the pending signal is an interference signal. For example, if the threshold of the signal power received by the destination node is A dbm, when the power of the pending signal is greater than or equal to A dbm, the pending signal is a source signal or a non-native signal, and the power of the pending signal is less than A. In the case of dbm, the pending signal is an interference signal.

Further, the channel estimation module 1022 is configured to perform channel estimation on the to-be-determined signal; specifically, the result of the channel estimation is information of a wireless channel, such as an order of a channel, a Doppler frequency shift, and a multipath delay or Parameters such as the impulse response of the channel. The signal determining module 1023 may determine, according to the information of the wireless channel, a signal transmission node that sends the to-be-determined signal, and thus, in combination with the result of the channel estimation and the result of the power check, the signal determining module 1023 may Determining whether the pending signal is a source signal or a non-native signal.

The signal synthesizing unit 104 may further include a phase adjustment module 1041;

Specifically, the phase adjustment module 1041 is configured to perform phase adjustment on the non-native source signal, so that the non-native source signal is in the same phase as its corresponding source signal.

In practical applications, since the source node and the non-native source signal are different from each other, the phase of the signal will be different. If the source signal and the non-native source signal are simply combined, the signal strength will be canceled. Therefore, Perform phase adjustment on non-native sources.

Further, the signal transmission node in the embodiment of the present invention not only receives the local source signal sent by the source node, but also receives the non-native source signal sent by the neighboring node, and synthesizes the two signals, Obtaining a signal with better signal quality; therefore, when the signal is generated, for example, when the signal transmitting unit 105 transmits the interference signal amplified by the signal to the destination node corresponding to the interference signal, the wide lobe signal can be used.

The neighboring node 30 is configured to receive the first signal sent by the source node 10, determine that the first signal is an interference signal, perform signal amplification on the first signal, and obtain a second signal to the destination node 20 Sending the second signal.

In practical applications, since the neighboring node 30 also needs to be the source node of other signal transmission nodes, there is also a fixed signal radiation angle; when the neighboring node needs to forward the signal to the destination node, it is necessary to adjust the fixed signal radiation angle, specifically The angle of the adjustment needs to be determined according to the layout of each signal transmission node; for example, referring to FIG. 4, in the signal transmission system, the layout of the signal transmission node is a lattice-like neat and symmetrical structure, and the angle of adjustment can be adjusted. It is 90 degrees, 180 degrees or 270 degrees. The ripple pattern between the two signal transmission nodes in the figure is a schematic diagram of the wide lobe signal. In the practical application of the embodiment of the present invention, the destination node and the neighboring node receive the first signal sent by the source node, and the first signal is regarded as the local source signal on the destination node side, and is regarded as the interference on the neighbor node side. After receiving the first signal, the neighboring node will amplify the signal to obtain a second signal, and then adjust the signal radiation angle to be forwarded to the destination node; for the destination node, the second signal forwarded by the neighboring node, It is a non-native signal and corresponds to the first signal having the same destination node.

Further, the destination node 20 determines that the signal types of the first signal and the second signal are respectively a source signal and a non-native source signal:

If the result of the channel estimation indicates that the node that sends the pending signal is the non-source node 10, the pending signal is a non-native signal.

Further, the destination node 20 synthesizes the first signal and the second signal to obtain a signal required by the local signal transmission node, specifically:

In the embodiment of the present invention, the signal transmission node not only receives the local source signal sent by the source node, but also receives the non-native source signal sent by the neighboring node, and synthesizes the two signals, so that a signal with better signal quality can be obtained. When the signal is transmitted, the source node 10, the destination node 20, and the adjacent node 30 use a wide lobe signal to perform signal transmission.
