Problems solved by technology

However, whether it is space shift keying or generalized space shift keying, under the condition of a certain number of antennas at the transmitting end, the spatial pattern is still small, and only through the maximum likelihood receiving algorithm can better receiving performance be obtained. Calculate high complexity

Abstract

The invention discloses a step-by-step encoding space shift keying method, a transmitting end encodes information bits step by step in multiple steps, so that the spatial degree of freedom of a multiple-input-multiple-output system is fully utilized, and the transmission rate of the system is improved. According to the step-by-step multi-step coding scheme provided by the invention, in the codingprocess of each step, different information bits are mapped, and finally a final-order to-be-coded vector is formed. A receiving end can adopt a maximum likelihood detection algorithm. In addition, the invention also provides a detection scheme based on orthogonal triangular decomposition. Compared with a traditional spatial domain modulation scheme, the step-by-step coding space shift keying scheme provided by the invention can obtain a higher transmission rate and better bit error rate performance.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a step-by-step coded space shift keying method. Background technique [0002] MIMO technology can provide array gain, space division multiplexing gain and diversity gain. Array gain can improve the signal-to-noise ratio of the received signal. Using space-time coding technology, MIMO communication system can provide diversity gain to resist channel fading and improve the robustness of system transmission. In the MIMO wireless communication system, using the space-time hierarchical structure, the MIMO communication system can provide space division multiplexing gain, transmit multiple data streams at the same time, and improve the transmission rate of the system. There is a trade-off between array gain, space division multiplexing gain, and diversity gain for MIMO techniques. [0003] Space keying is an effective way to achieve the benefits of MIMO technology. S...
