Abstract
Since the Multiple-Input Multiple-Output (MIMO) system is proposed, the technique becomes popular in the past decade because of the high channel capacity that it ob- tains. The spatial modulation (SM) is proposed, which has additional consideration about the energy efficiency, not only about the spectral efficiency. It means the power consumption of SM-MIMO is reduced in contrast to the spatial multiplexing systems. This thesis proposes a new transmission scheme for MIMO system based on the SM, is called Space-Time Permutation Code (STPC). STPC takes the advantage of the time diversity through the permutation modulation. The antenna selection across several time slots becomes the information for STPC, called permutation array (PA). STPC overcomes some difficult environments such as single receive antenna or highly corre- lated channel, which the conventional SM-MIMO is hard to apply. Moreover, STPC is flexible with the other transmission techniques such as Space-Time Coding (STC). The combination of STPC and STC makes the communication quality more reliable. Sphere decoding (SD) is introduced in this thesis, which is an efficiency decoder in contrast to Maximum Likelihood (ML) detector. And it keeps the decoding method to be optimal. The numerical simulation results present the comparison of STPC and the other trans- mission techniques. It shows that STPC is valuable to study further in the future, and apply in the Massive MIMO.
