Trellis Coding For Spatial Modulation [uzaysal Modulasyon İ?çi?n Kafes Kodlama]

Abstract

In this study by combining trellis coding with spatial modulation (SM) a new multiple-input multiple output (MIMO) communication scheme called trellis coded spatial modulation (TC-SM) is proposed. For uncorrelated Rayleigh fading channels code design criteria are given by deriving pairwise error probability (PEP) of this system in which a trellis encoder and SM mapper are jointly designed. These criteria are then used to obtain 4 8 and 16-states TC-SM schemes. It is shown via computer simulations that the proposed TC-SM schemes achieve better error performance than the classical space-time trellis codes with reduced decoder complexity. © 2011 IEEE.
