Embodiment

[0038] Examples of the present invention figure 1 As shown in -2, a relay method for a narrow pulse-based cooperative UWB communication system is implemented by the following parts, including a source node 1, a relay node 2, and a destination node 3, wherein the source node 1 is configured with a single The root antenna broadcasts signals to relay node 2 and destination node 3 through the wireless channel; after relay node 2 receives the signal from source node 1, it selects the relay link bit error probability according to the link information that has been obtained in advance The relay protocol with the best performance, and then send the signal to the destination node 3 through the antenna; the signal received by the destination node 3 comes from the direct link signal of the source node 1 or the relay signal from the relay node 2, The specific steps of the relay method are as follows:

[0039] A. The collaborative UWB communication system is ready to start work;

Abstract

The invention discloses a narrow pulse-based relaying method for a cooperative ultra wideband communication system, which belongs to the field of wireless communication. The system comprises a single information source node, a multiple relay node and a single target node. In the method, a channel state is characterized by distance information, and a control frame is required to be transmitted for one time only to determine distances among the nodes and a channel scene under the condition that communication nodes are still, so that overhead for transmitting control information is saved, and the throughput of the system is improved. Instantaneous information is not required to be exchanged, so ineffective power consumption for idle listening and control message overhead can be saved; therefore, node power consumption is lowered, and working time is prolonged. By the method, an adaptive relay protocol converting method is introduced to the relay node, the bit error rate of the cooperative ultra wideband system is reduced to the maximum, and the performance of the system is improved.

Description

technical field [0001] The invention relates to a relay method of a narrow pulse-based cooperative ultra-wideband communication system, and belongs to the field of wireless communication. Background technique [0002] Ultra-wideband technology, which uses extremely short-duration pulses to transmit signals, was first used in radar in the 1960s, and the U.S. Defense Advanced Projects Agency began using the term in 1990. Compared with other wireless communication systems, UWB communication systems have many advantages, such as low energy consumption, little interference to other existing wireless communication systems, high data transmission rate, and precise time resolution. Due to the above reasons, UWB is considered to be the most competitive technology for wireless personal area network communication in the future. [0003] The idea of ​​cooperative communication breaks the limitation of the number of antennas and terminal size of the MIMO system, and creates a virtual MI...
