Embodiment Construction

[0011] Below in conjunction with accompanying drawing, describe technical scheme of the present invention in detail:

[0012] In order to better describe the present invention, the terms used in the technical solution of the present invention and the transmitter structure of the generalized spatial modulation system are introduced here.

[0013] Generalized spatial modulation: assuming a GSM-MIMO system with N t root transmit antenna and N r Root receiving antennas, each time slot transmitting end only selects N p (N p t ) to transmit data symbols through the transmit antenna. Due to the N t Choose N among the root transmit antennas p The combination of root antennas has a total of , according to the bitmap rule, only need Antenna combinations are used for the mapping of information bits, Indicates rounding down. Therefore, similar to traditional spatial modulation, the information bits to be transmitted are divided into two parts, one part is used to select the co...

Abstract

The invention belongs to the technical field of communication, and relates to a receiving and sending end antenna selection method based on a channel norm of a generalized spatial modulation system. The invention provides the receiving and sending end antenna selection method based on the channel norm of the generalized spatial modulation system. According to the technology, a proper receiving and sending antenna set is selected according to channel information, the average SNR of a receiving end can be maximized, and the BER performance of the system is greatly improved under the condition that less feedback quantity is imported and lower complexity is increased for the system.

Description

technical field [0001] The present invention belongs to the technical field of communication anti-jamming, and relates to generalized spatial modulation (Generalized Spatial Modulation, SM) technology, quadrature amplitude (Quadrature Amplitude Modulation, QAM) modulation technology, and related MIMO (Multiple Input Multiple Output) technology, more specifically It is said to be a channel norm-based antenna selection method for the transceiver end of the generalized space modulation system. Background technique [0002] MIMO modulation technology is a high-speed transmission technology in a wireless environment. It configures more antenna units at the transmitting end and / or receiving end, and combines advanced space-time coding modulation schemes. By making full use of the degree of freedom of space, it can Brings additional diversity, multiplexing and beamforming gains. [0003] Recently, spatial modulation technique as a new MIMO modulation scheme has been proposed as a ...
