A New Approach for Adaptive Selection of Antennas in Spatial Modulation for Transceivers

A significant increase in spectrum efficiency is required to cope with the exponentially increasing traffic loads. These challenges the design of multipleinput multiple-output (MIMO) systems associated with the BS (Base Station). A typical long-term evolution BS consists of radio-frequency (RF) chains, direct current to direct current converters, cooling fans, etc. An adaptive antenna selection method for optimum transmission is proposed here. For multi stream MIMO, it aims to reduce the BER (Bit Error Rate) and average bit error probability (ABEP). It selects the best combination of signal and spatial constellation sizes, which minimizes the ABEP, BER. Results are also compared with the existing techniques.
