Space-time block codes (STBC) and spatial multiplexing (SM) are promising techniques that effectively exploit multipleinput multiple-output (MIMO) transmission to achieve more reliable communication and a higher multiplexing rate, respectively. In this paper, we study a practical design for hybrid scheme with multi-input multi-output orthogonal frequency division multiplexing (MIMOOFDM) systems...

In the present work, we have combined Orthogonal Space-Frequency Block Coding (OSFBC) and Spatial Multiplexing (SM) in one transmission scheme for Orthogonal Frequency Division Multiplexing (OFDM) systems. In the combined transmission scheme, both spatial diversity and multiplexing benefits are possible to achieve. Simple Alamouti coding as the S-F coding across spatial multiplexing branches an...

Multiple-input multiple-output spatial multiplexing (MIMO-SM) ultrawideband (UWB) systems with orthogonal frequency division multiplexing (OFDM) signaling are developed. It is shown that the proposed linear and nonlinear receivers offer substantial spatial diversity beside data rate enhancement.

Space-time block coding (STBC) and Spatial multiplexing (SM) or BLAST (Bell Labs Layered Space-Time) are promise approaches that exploit the MIMO channel to provide higher data rates and diversity gains with no sacrifice in bandwidth. In this work, we present a hybrid MIMO scheme that combines transmit diversity and spatial multiplexing. The proposed scheme can achieve arbitrary number of multi...

This chapter addresses the problem of multiplexing multiple data streams in a multiple input multiple output (MIMO) system in the presence of channel matrix ill-conditioning brought by fading correlation and/or a Rice component. Conventional multiplexing schemes based on the separation of the stream’s spatial signatures (commonly referred to as spatial multiplexing—SM, V-BLAST architecture) rel...

In multiple antenna transmission the multiplexing gain strictly depends on transmit and receive antenna allocation, transmit antenna synchronization and the process used to eliminate the inter channel interference (ICI). Spatial modulation (SM) is a low-complexity scheme for multiple antenna system. The work and research on Spatial Modulation shows that SM is useful to achieve the multi block-c...

This paper exploits Application Layer Forward Error Correction (AL-FEC) based on Raptor codes to achieve for reliable video multicast over 802.11n multiple-input multipleoutput (MIMO) channels. The system performance and cross-layer optimisation parameters are analysed for spatial multiplexing (SM) waveforms under different channel conditions and quality of service requirements. Results show th...

This work was supported by the Brain Korea 21 Project. Abstract−The effective applications of the proportional fair scheduling (PFS) scheme are investigated for the downlink of a cellular system with multiple transmit and receive antennas. We propose an improved PFS scheme based on spatial multiplexing (SM), referred to as P-PFS/SM, after reviewing the conventional PFS scheme based on spatial d...

In recent years, the remarkable ability of multiple-input multiple-output (MIMO) wireless communication systems to provide spatial diversity or multiplexing gains has been clearly demonstrated. For MIMO diversity schemes, it is well known that antenna selection methods that optimize the post-processing signal-to-noise ratio can preserve the diversity order of the full MIMO system. On the other ...

The demand for high data rate in wireless communication has increased dramatically over the last two decades. Multiple-Input Multiple-Output (MIMO) transmission is one of the efficient ways to transmit high data rate is by employing multiple antenna configuration at both the transmitter and the receiver. One of the MIMO scheme, known as Spatial Multiplexing (SM), relies on the linear independen...
