Selective Transmitter Diversity and Channel Inversion for Mobile Radio Systems
نویسندگان
چکیده
Transmitter diversity at the base station of a cellular mobile radio system provides a means to achieve performance gains similar to those obtained with mobilestation receiver diversity, but without the complexity of a mobile-station receiver antenna array. We investigate Selective Transmit Diversity (STD) in the downlink of the Wideband Code Division Multiple Access (WCDMA) mobile radio channel system. For fast vehicle speeds, we utilize long range fading prediction to enable performance of the STD system for standard stationary fading models, as well as for a novel physical model that accounts for the realistic nonstationarity of the fading channel. Finally, we evaluate the gain of the combined STD and the truncated channel inversion power control method.

Cyclic Delay Diversity: Effective Channel Properties and Applications
We briefly explain the concept of cyclic delay diversity (CDD) as a variant of standard conformable delay diversity techniques. Usually being implemented at the transmitter side of an OFDM based system, the application of CDD is recognized at the receiver side only by observing modified channel propagation conditions. Therefore, we analyze the effect of CDD on the channel fading properties obse...
متن کاملThe Doppler spread - gaining diversity for future mobile radio systems
In this paper the trade-off between time diversity and the inter-carrier interference (ICI) in an OFDM based MC-CDMA system is discussed. Our approach is to partially shift each spectrum of an OFDM symbol at the transmitter by using different phase shifts in the time domain at different antennas after the OFDM modulation. The summary signal at the receiver has a wider Doppler spectrum as the re...

Adaptive transmission techniques such as adaptive modulation and transmitter antenna diversity have been proposed for mobile wireless systems to satisfy high data-rate service requirements. In rapidly time variant channels, these methods need the knowledge of future fading conditions and therefore require accurate long range fading prediction. We investigate three combined adaptive modulation...

In this paper, we investigate broadband OFDM systems which apply beamforming in combination with different space–time diversity techniques. Various beamforming scenarios with transmitter and/or receiver sided beamforming are considered. Space–time diversity is obtained by cyclic delay diversity (CDD) in order to artificially shape the spectrum of the received signal. Thus, an advantageous distr...
متن کاملAnalysis of compact Arrays for MIMO based a on complete RF System Model
A model for an extended MIMO transmission channel including transmitter, receiver, antennas and the physical channel is presented. For the analysis of compact MIMO systems for small handheld devices, it is inevitable to consider this extended model, since the antennas couple and interact, which influences both SNR and the channel matrix H. Capacity calculations for diversity and beamforming bas...
