Maximum Combination Spatial Modulation

Abstract

Spatial Modulation (SM) is a variant of the Multiple-Input Multiple-Output (MIMO) technique with only one antenna transmits signal at a time. It has the advantage of inter-antenna interference avoidance. Therefore, most of the antennas are idle during the signal transmission. Many literatures have been proposed to use multiple antennas to improve the bit error rate (BER) and bandwidth efficiency for the SM. In this paper, we propose a maximum combination spatial modulation (MCSP) to improve the Bit Error Rate (BER) performance of the related SM methods. Results show that the proposed method can improve the BER and can also increase the throughput for the conventional SM method.
