Efficient OFDM transceiver design for VLC sys-tems in fading channel

Optimal PRCC Coded OFDM Transceiver Design for Fading Channels

In this paper, an adaptive receiver for efficient inter carrier interference (ICI) cancellation in OFDM systems using two-path conjugate transmission is proposed. This receiver design is based on the phase rotated conjugate cancellation (PRCC) concept, where one common phase rotation is applied to the two transmit paths. An adaptive normalized block least mean-squared algorithm is used for the ...

Interpreting voice commands in radar sys- tems

This master’s thesis is done in collaboration with SAAB and outlines an architecture for developing a voice command system with focus on supporting multiple languages, ease of introducing new domain knowledge, resource efficient and running in an offline environment. The solution and the decisions made along the process as well as their advantages and drawbacks are explained in this report. As ...

Composite Fermions in Quantum Hall Sys- Tems

— The occurrence of incompressible quantum fluid states of a two dimensional system is a result of electron–electron interactions in a highly degenerate fractionally filled Landau level. Novel quasiparticles (QP’s) called composite Fermions (CF’s) have allowed a simple single particle description of the most prominent incompressible states. Residual interactions among these QP’s are investigate...

Time-Varying Frequency Fading Channel Tracking In OFDM-PLNC System, Using Kalman Filter

Physical-layer network coding (PLNC) has the ability to drastically improve the throughput of multi-source wireless communication systems. In this paper, we focus on the problem of channel tracking in a Decode-and-Forward (DF) OFDM PLNC system. We proposed a Kalman Filter-based algorithm for tracking the frequency/time fading channel in this system. Tracking of the channel is performed in the t...
