The authors investigate the MIMO antenna selection using Space Shift Keying (SSK) modulation and Amplitude/Phase Modulation (APM). In the joint SSK and APM, both the constellation of APM and the antenna indexes of SSK convey information. The Multiple-Input Multiple-Output (MIMO) system increases the capacity and data rates at the cost of the multiple RF chains, which can be reduced by antenna selection techniques. In this paper, the antenna selection techniques are jointly designed with the SSK-based MIMO systems, and the decoding scheme achieving Maximum-Likelihood (ML) criterion is explicitly described. The proposed antenna selection criteria pursue the best antenna configuration by utilizing channel state information.
