Abstract
Generalized Spatial Modulation (GSM) technology is a new multiple-input multiple-output (MIMO) technique that can improve spectral efficiency in wireless communication systems. In this paper, a generalized spatial modulation based on array-blocks (AB-GSM) scheme is proposed for the mmWave high speed railway (HSR) communication systems. In the proposed AB-GSM scheme, GSM is adopted at transmitter and more than one array-blocks are simultaneously activated at the base station (BS) to transmit data. Modulated symbols are transmitted by using the radio frequency (RF) beamforming technology. The information bit rate and bit error rate (BER) performance of the AB-GSM system under mmWave channel model are investigated. Theoretical analysis and simulation results show that the proposed AB-GSM scheme has a considerable improvement in the data transmission rate and spectral efficiency compared with the traditional GSM.
