Problems solved by technology

[0004] The present invention aims at the technical problem that the system performance after configuration in the multi-carrier wireless repeater station configuration method is far lower than the modern communication requirements, resulting in excessive signaling loss and system complexity in the wireless communication system of carrier multi-carrier stations, and proposes A three-step resource optimization configuration method for multi-carrier wireless repeater stations. For a pair of multi-carrier switching nodes, it only needs to allocate up to two repeater stations according to three simple steps each time, and then increase the signal transmission power of the transmitter , the stability of the optimal system can be achieved

Embodiment Construction

[0040] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly defined.

[0041] like figure 1 , figure 2 As shown, the implementation environment and process of a three-step multi-carrier wireless repeater resource optimization configuration method in this embodiment: in the multi-carrier multiple repeater two-hop cooperative communication system, there is a pair of switching nodes, which are used as the source and The sink has 4 repeaters (M=4) and 8 carriers (K=8). Assuming that through network detection and channel estimation, we obtain the direct transmission channel gains of 8 carriers as shown in Table 1:

Abstract

The invention relates to the field of communication network technology and smart city service support, and discloses a three-step multi-carrier wireless repeater station resource optimization configuration strategy, comprising the following steps: Step 1: After initialization, obtain detection information by detecting communication environment and network information ; Step 2: classify the independent subcarriers obtained in step 1 according to the subcarrier classification criteria to obtain a direct transmission subcarrier set and a forwarding subcarrier set; Step 3: judge the direct transmission subcarrier set and forwarding obtained in step 2 Whether the subcarrier set is an empty set, different transmission modes are adopted for different situations. For a pair of multi-carrier switching nodes, the present invention only needs to allocate at most two forwarding stations according to three simple steps each time, and then by increasing the signal transmission power of the transmitting end, the stability of the optimal system can be achieved.

Description

technical field [0001] The invention relates to the field of communication network technology and smart city service support technology, and more particularly, to a three-step multi-carrier wireless repeater station resource optimization configuration method. Background technique [0002] In modern communication systems, with the continuous improvement of the number of access users and communication throughput, multi-carrier wireless communication protocols and frameworks based on orthogonal frequency division multiplexing are becoming more and more common. Most of the user-oriented wireless communication systems are multi-carrier communication systems. At the same time, as the coverage of the communication network becomes wider and wider, the cooperative communication based on the wireless relay station is also widely used as an auxiliary communication means to improve the overall performance of the wireless communication network. The wireless repeater provides a two-hop t...
