Embodiment Construction
[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0044] The invention provides a multi-terminal parallel communication method based on a multi-antenna spread-spectrum signal detection mechanism, through the two-level action areas of code selection and terminal detection, and simultaneously completes the acquisition of multiple node information. Such as figure 1 shown, including the following steps:
[0045] S1 determines the task area. Node communication terminals are deployed on the nodes entering the task area. Each node has a unique number with a length of 8 bits. A Multiple Antennas Base Station (Multiple Antennas Base Station) is deployed a...

The invention provides a multi-terminal parallel communication method based on a multi-antenna spread spectrum signal detection mechanism, aimed at defects of device mounting complexity, no way of eliminating adjacent channel interference and the like in the prior art. The method comprises the steps of respectively deploying a multi-antenna array base station unit at the inlet and outlet of a taskregion and deploying a node communication terminal at each node; the node communication terminal determining a spectrum code used for transmission of the current terminal by using a sorting spectrumcoding selection mechanism at a code selection phase; and at a terminal detection phase, the multi-antenna array base station unit using a multi-terminal parallel detection mechanism to finish detection of multiple pieces of node terminal information. The multi-terminal parallel communication method based on a multi-antenna spread spectrum signal detection mechanism in the invention has the characteristics of high detection success rate, low complexity, small signal processing delay and the like; and the multi-antenna array base station unit can quickly count the entry and exit status of taskregion node.
Description
technical field [0001] The invention relates to the technical field of wireless signal processing of a broadband ad hoc network, in particular to a multi-terminal parallel communication method based on a multi-antenna spread spectrum signal detection mechanism. Background technique [0002] With the gradual maturity of artificial intelligence and Internet of Things technologies, there are more and more tasks for large-scale unmanned nodes to carry out group activities. However, for a long period of time, unmanned and manned mixed tasks will occupy a relatively high proportion. The coordination between human and human has become a great challenge. Taking the collaboration between unmanned vehicles and traditional manned vehicles as an example, how to publish and share vehicle status and road information at different driving speeds and driving states? How to make effective statistics on the status of nodes without affecting the execution of tasks of each node is a big proble...
