In this paper, we investigate the possibility, from an energy efficiency point of view, of employing Analog Network Coding in the Multiple Access Relay Channel (MARC) instead of the conventional Time-Division Multiple Access (TDMA) protocol when time and not bandwidth is the available resource in the network. Towards this end, we derive a closed-form upper bound of the Bit Error Rate (BER) per source...
In this paper, we provide a theoretical analysis of the optimal Maximum-Likelihood (ML) detector for the recently proposed multistream Spatial Modulation (SM) concept for multiple-input-multiple-output (MIMO) systems. A Union Bound that is based on closed-form formulas is derived for the average bit error probability (ABEP) of the ML detection, which shows an excellent fit with respect to Monte Carlo...
In this paper, we propose a closed-loop and single RF multiple-input-multiple-output (MIMO) method, particularly suitable for the Uplink of cellular systems, which is based on the low-complexity and recently devised method of Spatial Modulation. By selecting a subset of the available transmit antennas to implement Spatial Modulation based on the instantaneous Bit Error Rate (BER), the proposed method...
