• Massive spatial modulation (MSM) is considered as an appealing technique for multi antenna wireless communications. Massive SM-MIMO utilizes multiple transmit antennas (TAs) for every user with one radio frequency (RF) chain and hundreds of antennas at base station (BS) with little number of RF chain. Owing to a big number of TAs at the user and little number of RF chains at BS, signal detection turns into challenging issue. To resolve this issue, a joint grouped SM transmission scheme at users and signal detection based on group subspace pursuit (GSP) at BS can be suggested to get better the performance of signal detection. In addition to, the cyclic prefix single carrier (CPSC) is utilized to withstand the multipath channels. Simulation results prove that BER performance of the suggested signal detection based on GSP outperforms classical signal detection based on SP by 3dB SNR gain at BER=10 -4 .
