Problems solved by technology

In order to improve the signal-to-noise ratio of the FBMC system in the massive MIMO channel, due to the self-balancing property of the channel, the SINR should increase correspondingly when the number of antennas increases, but the channel equalization method proposed in the existing literature has higher computational complexity

Abstract

The present invention discloses a design method of an FBMC transceiver system based on an FRM technology in a 5G system. The method comprises the steps of designing a half-band prototype filter by using a mirroring technology, then, performing frequency masking on the half-band prototype filter by using the FRM technology, and finally, modulating the half-band prototype filter into an integrated filter bank and an analysis filter bank through Discrete Fourier transform, in a large-scale MIMO channel, completing an SINR saturation value test of the FBMC system by increasing antennas, and analyzing a result. Due to the narrow transition band designed by using the FRM technology and the prototype filter suited to any bandwidth, the signal to noise ratio of the FBMC system can be improved, further, the upper limit of the SINR saturation value can be acquired, and correlation interference caused by increase of base station antennas is eliminated. The structure of the sytem is novel and reasonable, and the system is less complex to realize, so that the large-scale MIMO communication system based on the FBMC transceiver system is more effective and reliable.

Description

technical field [0001] The present invention relates to the communication field, in particular to a design method of an FBMC transceiver system based on FRM technology in a 5G system. Background technique [0002] With the development of the information age, modern communication systems increasingly require the improvement of data transmission rate and capacity. In the case of limited existing spectrum resources, improving spectrum utilization has become an urgent problem to be solved in mobile communication systems. Therefore, In recent years, 5G mobile communication technology has become an important topic of great concern and research in the industry. As the key technologies, FBMC system and MIMO system have also received extensive attention. In comparison, filter bank multi-carrier technology (FBMC), as one of the candidate technologies for the physical layer of 5G, has received attention because of its higher spectrum utilization and lower out-of-band radiation. Due to...
