Integrated Spatial Modulation and STBC-VBLAST Design toward Efficient MIMO Transmission [PDF]

open access: yesSensors, 2022
In this contribution, the concept of spatial modulation (SM) is firstly integrated into the structure of space-time block codes (STBC)-aided vertical Bell-labs layered space-time (VBLAST) systems, in order to strike a balanced tradeoff among bit error ...

Quasi-orthogonal STBC with minimum decoding complexity

open access: yesIEEE Transactions on Wireless Communications, 2005
In this paper, we consider a quasi-orthogonal (QO) space-time block code (STBC) with minimum decoding complexity (MDC-QO-STBC). We formulate its algebraic structure and propose a systematic method for its construction. We show that a maximum-likelihood (ML) decoder for this MDC-QOSTBC, for any number of transmit antennas, only requires the joint ...

Iterative Frequency-Domain Receivers for STBC Schemes [PDF]

open access: yes2009 IEEE 70th Vehicular Technology Conference Fall, 2009
In this paper, we consider iterative frequency- domain receivers for block transmission techniques with rate-1 Space Time Block Coding (STBC) for two or four transmit antennas. We consider both Orthogonal Frequency Division Multiplexing (OFDM) and Single- Carrier (SC) schemes.

PERFORMANCE AND CAPACITY COMPARISON BETWEEN HYBRID BLAST-STBC, VBLAST AND STBC SYSTEMS [PDF]

open access: yes, 2012
The hottest issue of next generation communication systems is data throughput improvement for any wireless channel conditions. MIMO systems are the key techniques for the next generation communication systems. BLAST systems achieve high data rates with acceptable BER performance over a good channels state while STBC systems can achieve better BER ...
