Adaptive Selection of Antennas for Optimum Transmission using STBC

Adithya. B

In this paper, we propose an optimum transmit structure using STBC instead of spatial modulation (SM) in a multiple-input multiple-output (MIMO) transmission technique. Based on transmission optimized spatial modulation (TOSM), selects the best transmit structure that minimizes the average bit error probability (ABEP). Unlike the traditional antenna selection methods, the proposed method relies on statistical channel state information (CSI) instead of instant CSI, and eigen value and feedback is needed for the optimal number of transmit antennas. The overhead for this, however, is negligible. In addition, TOSM has low computational complexity as the optimization problem is solved through a simple closed-form objective function with a single variable. Simulation results show that TOSM and STBC significantly improves the performance of various channel correlations. We propose a single radiofrequency (RF) chain base station (BS) based on TOSM, which achieves low hardware complexity and high energy efficiency. In comparison with multi-stream MIMO schemes, TOSM and STBC offers an energy saving of at least 56 % in the continuous transmission mode, and 62 % in the discontinuous transmission mode.
