Problems solved by technology

However, spatial modulation also inherits the limitations of traditional modulation methods: the number of transmitting antennas must be a power of 2, such as 2, 4, 8, 16..., etc., and cannot support a flexible number of antenna configurations

Abstract

The invention discloses a space modulation transmission method. The method comprises steps: M transmitting antennas are selected from Nt transmitting antennas, wherein 0< / =M< / =Nt, M is the power of 2, space modulation mapping is carried out on data loaded in the M transmitting antennas; if M<Nt, data loaded in Nt-M transmitting antennas except the M transmitting antennas and data loaded in min{M,(Nt-M)} in the M transmitting antennas are subjected to space-time coding; and data after coding are transmitted. The invention also discloses a space modulation transmission device. When the technical scheme disclosed by the invention is applied, power-of-two constraints of the transmitting antenna number in the traditional system can be broken through, flexible antenna configuration is supported, and the performance of the system is effectively enhanced.

Description

technical field [0001] The invention belongs to the technical field of communication anti-jamming, and in particular relates to a space modulation transmission method and equipment. Background technique [0002] Spatial Modulation (Spatial Modulation, SM) technology is a new multiple input multiple output (Multiple Input Multiple Output, MIMO) transmission technology proposed in recent years, which can also be regarded as a new modulation technology using antenna resources. The basic principle of this technology is: by activating different transmit antennas, the index value of the activated antenna is used to modulate the bit information. Only one antenna is activated for each time slot of spatial modulation, thus effectively avoiding the problems of multi-antenna interference and synchronization between transmitting antennas in traditional MIMO systems, and reducing the implementation cost of MIMO systems. This technology has aroused widespread concern in the industry. ...
