Blind Vector Channel Estimation for Differentially Modulated Systems with Transmit Diversity
نویسندگان
چکیده
We consider vector channel estimation for differentially modulated systems with transmit diversity. We propose a blind estimation scheme to yield superior performance to that of the pilot-aided estimation. The proposed scheme utilizes the repeated transmission of space-time coded data symbols. We compare the performance of the proposed blind scheme with the pilot-based estimation scheme via computer simulations. key words: vector channel estimation, space-time block coding, transmit diversity

Spectrally efficient transmit diversity scheme for differentially modulated multicarrier transmissions
Cyclic delay diversity is a simple, yet effective, transmit diversity scheme for multicarrier based transmissions employing coherent digital linear modulation schemes. It is shown that, for satisfactory operation, the scheme requires additional channel estimation overhead compared to single antenna and traditional space–time coded transmissions owing to the inherent increase in frequency select...
متن کاملReduced-Complexity Vector Channel Estimation for Systems with Receive Diversity
We consider a blind estimation of the vector channel for systems with receive diversity. The objective of this paper is to reduce the complexity of the conventional subspace-based method in vector channel estimation. A reduced-complexity estimation scheme is proposed, which is based on selecting a column of the covariance matrix of the received signal vectors. The complexity and performance of ...
متن کاملDirection-time transmission for fast fading vector channel
Transmit diversity and space-time coding have received a lot of attention in recent years. In this paper, we propose a direction-time transmit scheme for a fast block fading channel which exploits the parametric structure of the time-varing vector channel. Specular propagation and local scattering are assumed at the base-station and mobile station respectively. The partial channel knowledge nee...
متن کاملTransmit Delay Structure Design for Blind Channel Estimation over Multipath Channels
Wireless communications often exploit guard intervals between data blocks to reduce interblock interference in frequency-selective fading channels. Here we propose a dual-branch transmission scheme that utilizes guard intervals for blind channel estimation and equalization. Unlike existing transmit diversity schemes, in which different antennas transmit delayed, zero-padded, or timereversed ver...

In this paper an Importance Sampling technique is proposed to achieve blind equalizer and detector for chaotic communication systems. Chaotic signals are generated with dynamic nonlinear systems. These signals have wide applications in communication due to their important properties like randomness, large bandwidth and unpredictability for long time. Based on the different chaotic signals prope...
