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)
— Cognitive radio technology facilitates spectrum reuse and alleviates spectrum crunch. One fundamental problem in cognitive radio is to avoid the interference caused by other communication systems sharing the same frequency band. However , spectrum sensing cannot guarantee accurate detection of the interference in many practical situations. Hence, it is(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)
