Space shift keying transmission system receiving end data detection method based on layered detection

The invention discloses a space shift keying transmission system receiving end data detection method based on layered detection. The method includes the following steps that firstly, a receiving end model is determined; secondly, the receiving end model is simplified; thirdly, sent data are demodulated through a layered detected algorithm. According to the space shift keying transmission system receiving end data detection method based on layered detection, the bit error rate (BER) performance of the method is gradually similar to that of an optimal detection (ML) algorithm along with the increase of the search radius, and when the search radius is equal to the number of antennas at the sending end, the detection algorithm is equivalent to a maximum likelihood detection algorithm. Calculation ranking is conducted on each layer through the algorithm, the bit error rate performance of the method can be similar to that of the optimal detection algorithm in the small search radius, and therefore the method has the advantages that good performance can be acquired, and the complexity of the algorithm at the receiving end is greatly lowered.
