Effect of Channel Correlation on the Performance of Space-Time Coded Systems

چکیده
Abstract — For a space-time coded system in a correlated Rayleigh fading environment, we consider two receiver structures: (1) a suboptimum one in which the imperfect channel state information (CSI) is used in place of perfect CSI in a perfect CSI optimum receiver, (2) the optimum receiver in which the imperfect CSI is used in the maximum likelihood sense. Channel estimation is done by the use of a pilot code matrix prior to data reception. In the cases of both the receivers, the system performance is analyzed in terms of the pairwise error probability.

The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems.

متن کاملSpace-Time Coding and Space-Time Channel Modelling for Wireless Communications
In this thesis we investigate the effects of the physical constraints such as antenna aperture size, antenna geometry and non-isotropic scattering distribution parameters (angle of arrival/departure and angular spread) on the performance of coherent and non-coherent space-time coded wireless communication systems. First, we derive analytical expressions for the exact pairwise error probability ...
متن کاملMatched Filter Bound for Space-Time Block Coded MIMO Systems in Correlated Multipath Fading
The matched filter bound for space-time block coded multiple-input multiple-output systems in a frequency-selective Nakagami fading channel is derived for binary phase shift keying. Arbitrary correlation among the elements of the transmitter and the receiver antenna arrays is taken into account. Moreover, in the special case of Rayleigh fading the effect of the pulse shape is also considered. T...
