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 space-shift keying method of step-by-step coding, wherein the transmitting end uses step-by-step multi-step coding of information bits, thereby making full use of the space degree of freedom of the multi-input multi-output system and improving the transmission rate of the system. In the step-by-step multi-step encoding scheme proposed by the present invention, different information bits are mapped in each step of the encoding process, and finally the final order vector to be encoded is formed. The receiving end can adopt the maximum likelihood detection algorithm, and the present invention also proposes a detection scheme based on orthogonal triangular decomposition. Compared with the traditional space domain modulation scheme, the progressive coding space shift keying scheme proposed by the present invention can obtain 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...
