Embodiment Construction

[0011] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings:

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

[0013] Generalized spatial modulation: assuming that the GSM-MIMO system has N t Root transmitting antenna and N r One receiving antenna, only N is selected at the transmitting end of each time slot p (N p t ) A transmitting antenna transmits data symbols. Because in N t Select N among the transmitting antennas p There are a total of antenna combinations According to the bit mapping rules, only 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 tra...

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 field of communication anti-interference technology, and relates to generalized spatial modulation (Generalized Spatial Modulation, SM) technology, quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM) modulation technology, and related MIMO (Multiple Input Multiple Output) technology, more specifically It is a method of antenna selection at the transceiver end of a generalized spatial modulation system based on the channel norm. Background technique [0002] MIMO modulation technology is a high-speed transmission technology in a wireless environment. It is equipped with more antenna units at the transmitting end and / or receiving end, and combined with advanced space-time coding modulation schemes. Through the full use of spatial freedom, it can Brings additional diversity, multiplexing and beamforming gains. [0003] Recently, spatial modulation technology as a new MIMO modulation scheme has been propose...
