Dedicated to my mother and the memory of my father ii Acknowledgement I would like to acknowledge my supervisor, Dr. C. P. Kwong, who introduced me the sequence estimation problem and encouraged me to look at it from new viewpoints. It is also him who taught me the right attitude, which I believe every true researcher ought to have, towards a difficult(More)
— Recently, lattice-reduction-aided detectors have been proposed for multiple-input multiple-output (MIMO) systems to give performance with full diversity like maximum likelihood receiver, and yet with complexity similar to linear receivers. However, these lattice-reduction-aided detectors are based on the traditional LLL reduction algorithm that was(More)
— This paper analyzes bit error rate (BER) and outage probability of singular value decomposition-based multiple-input multiple-output systems with channel estimation error and feedback delay over uncorrelated Ricean fading channels. By utilizing marginal unordered and ordered eigenvalue distributions of complex noncentral Wishart matrices, we derive exact(More)
2115 in the CFO estimation can still be achieved. We have also studied the optimal free null subcarrier placement problem for practical OFDM systems with guard bands. We have demonstrated that the proposed null subcarrier placement significantly improves the performance of the CFO estimation. ACKNOWLEDGMENT The authors would like to thank Prof. T. J. Lim(More)
As 2D barcodes become more and more popular, their new applications, like mobile marketing, give a strong motivation for embedding visual information in them. Information stored on a 2D barcode, being printed on paper or shown on a display device, can be delivered to people via a camera phone with suitable decoding software. The barcoding system can be(More)
