Blind Acquisition of Short Burst with Per-Survivor Processing (PSP)
… use of Maximum Likelihood Sequence Estimation (MLSE) in the presence of unknown channel parameters. MLSE is a fundamental problem that is closely related to many modern research areas like Space-Time Coding, Overloaded Array Processing and Multi-User Detection. Per-Survivor Processing (PSP) is a …

CPM Equalization to Compensate for ISI due to Band Limiting Channels
… response so that we can use a low complexity MLSE equalizer. We implement the channel truncation structure by Falconer and Magee and adapt it to work with CPM signals. This structure uses a, a more derivable, pre-filter to shape the overall response of the channel, so that its impulse response …

Adaptive Equalization for Indoor Channels
… and the maximum-likelihood sequence estimation (MLSE) equalizer. This work also covers adaptive algorithms for equalization including both the least mean squares (LMS) and the recursive least squares (RLS) algorithm. All these equalizer structures and algorithms will be modeled using various …

Minimum-delay HF communications
… time-varying ISI channels, producing a robust MLSE receiver with several milliseconds of decision-making delay. Finally, we cascade this MLSE receiver with MAP detection to obtain high-fidelity low-delay performance, finding a practical solution to minimum-delay HF communications.

Coding and Equalization for Radio Channels
… maximum-likelihood sequence estimation (MLSE), reduced-state sequence estimation (RSSE), and combined minimum-mean-square error decision-feedback equalization (MMSE-DFE) and Viterbi decoding.

Simulation of adaptive equalization in two-ray, SIRCIM, and SMRCIM mobile radio channels
… and the maximum likelihood sequence estimation (MLSE) equalizer. Least mean square (LMS) and recursive least squares (RLS) algorithms are used as the adaptive algorithms for these equalizers. Lattice-DFE, DFE, and MLSE with an RLS algorithm are recommended to be implemented in mobile systems …

Decoding algorithms for continuous phase modulation
… called maximum likelihood sequence estimation (MLSE). Another way to do MLSE would be to correlate all possible transmitted sequences (reference signals at the demodulator) over a period of N symbol intervals with the received sequence. The first symbol of the reference sequence with which the …

Transmission and detection for space-time block coding and v-blast systems
… selective fading channels. The proposed MLSE detection scheme effectively combats channel dispersion and frequency selectivity due to multipath, yet still provides full diversity gain. However, since the computational complexity of MLSE detection increases exponentially with the maximum …

Iterative Decoding and Channel Estimation over Hidden Markov Fading Channels
… either maximum likelihood sequence estimation (MLSE) algorithms or maximum <I> a posteriori</I> (MAP) algorithms operating over the trellis defined by the MFC can be used for channel estimation. Furthermore, the thesis illustrates sequential and decision-directed techniques for using the …

A likelihood ratio analysis of digital phase modulation
… for maximum likelihood sequence estimation (MLSE). A useful notation, called the likelihood transform, was presented to aid the analysis of likelihood ratios. The work concentrated initially on computer-aided searches, first for trellis codes which may give rise to simplifying likelihood …

Very High Speed Coherent Passive Optical Networks
… with non-linear equalisers, such as Volterra or MLSE were studied. The solution was shown to exceed N1 class requirements. The above mentioned solutions were combined and tested bidirectionally on both lab and field installed fibre. Testing on 20 km and 40 km in the lab, as well as 19 km of field …
