In this paper, we propose a relay assisted multiuser Multiple-input multiple-output wireless communication using multilayer space time block coding in the presence of Rayleigh fading. Bit error rate, capacity, diversity and multiplexing gain are investigated for the proposed scheme. Information of each user is modulated using QPSK or 16QAM or 64QAM modulator and modulated data are further encoded...
In this paper, performance of STBC, VBLAST, MLSTBC and Hybrid-STBC-VBLAST is investigated in the presence of rayleigh fading for relay assisted multiple access communication. STBC provides diversity gain but does not provide multiplexing gain. On the other hand, VBLAST provides multiplexing gain but does not provide diversity gain. But combination of STBC and VBAST scheme such as MLSTBC and HYBRID-STBC-VBLAST...
In this paper, performance of Multi-Layered STBC (MLSTBC) is investigated in the presence of Rayleigh fading for relay assisted Multiple-Input Multiple-Output (MIMO) system. Space Time Block Coding (STBC) is used for encoding the information at user's handset because the channel from handset to relay is bad-state channel and STBC is more suitable for bad-state channel to obtain low BER. On the other...
