Abstract
In this paper, we propose a combination of the vertical layered Space-Time architecture (V-BLAST) and the Space-Time Block Codes (STBC) producing VBLAST-STBC, which shows a performance advantage over V-BLAST in flat fading channels. We also propose VBLAST-STBC with Orthogonal Frequency Division Multiplexing (OFDM) producing VBLAST-STBC-OFDM, which shows a performance advantage over VBLAST-OFDM infrequency selective fading channels. These two schemes provide reliable as well as very high data rate communications over Rayleigh fading channels. The simulations show the advantages of the proposed schemes over the original V-BLAST and VBLAST-OFDM schemes.
