Performance Analysis of STBC MB-OFDM UWB

2009 6th IEEE Consumer Communications and Networking Conference, 2009
This paper addresses the performance analysis for orthogonal space-time block coded (STBC) multiband orthogonal frequency division multiplexing (MB-OFDM) ultra-wideband (UWB) systems. As the channel model considers the log-normal fading, the resultant signal to noise ratio (SNR) will be the product of a log-normal distributed variable and a variable of

STBC-VBLAST for MIMO Wireless Communication Systems

IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005
The vertical Bell-labs layered space-time (VBLAST) scheme can be used to exploit the capacity potential provided by multiple transmit antenna systems. In VBLAST systems, detection and decoding are performed layer by layer in a successive way. However, successive processing degrades performance because of the low minimum diversity and error propagation.

STBC MIMO OFDM Systems with Implementation Impairments

2008 IEEE 68th Vehicular Technology Conference, 2008
Multi-input multi-output (MIMO) systems are often realized with low cost front-end architectures, e.g. the so called direct conversion architectures. However, such systems are very sensitive to imperfections in the analog front-end, resulting in radio frequency (RF) impairments such as in-phase/quadrature-phase (IQ) imbalance and carrier frequency ...

Two-way quantize-and-forward relaying with STBC

2012 25th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2012
In this paper we propose a new two-way relaying scheme using a quantize-and-forward strategy with space-time block coding (STBC). In this scheme two nodes use STBC to simultaneously transmit their signals to the relay. At the relay these signals are estimated by using minimum mean square error ordered successive interference cancellation and then are ...

STBC-DFE Systems with Different Factorization Algorithms

2006 Canadian Conference on Electrical and Computer Engineering, 2006
A Multiple-Input-Multiple-Output (MIMO) system in which Space-Time Block Coded (STBC) signals are equalized by a Decision Feedback Equalizer (DFE) is presented in this paper. Three factorization algorithms including band LU, band LDL and band Cholesky factorization are used to obtain the optimum feedback and feedforward filter matrices of the STBC-DFE ...

A Differential STBC Integrated with Trellis Coded Modulation

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2005
We introduce a differential space-time block code (DSTBC) integrated with trellis coded modulation with two transmit antennas. Our scheme enables transmission of DSTBC encoded symbols as trellis metric rather than concatenating an outer code. Unlike conventional DSTBC, different transmit symbol phase rotations are used for each transmit antenna in ...
