Abstract
Space Shift Keying is a MIMO transmission scheme that has been recently studied as a promising solution for low computational complexity devices. Such a scheme is based on the concept of spatial modulations (SM) where the information is mapped to the index of the transmit (resp. the receive) antenna. When only one antenna is used per symbol duration, an SSK symbol is able to transmit base 2 log of the number of transmit antenna ( $N_{t}$ ). An extended version of the conventional SSK scheme, referred to as Extended SSK (ESSK) has been recently proposed. The proposed technique allows the overall spectral efficiency to be increased such that the total amount of bits reaches $N_{t}$ instead of $\log_{2}(N_{t})$ in conventional approaches. In this paper, we evaluated the performance of ESSK scheme with different detection strategies. Analytical results have been also validated through simulations.
