Coding and Equalization for Radio Channels
… channels introduce intersymbol interference. Equalization can be employed for such channels if the time variation is slow. In this thesis, three equalization methods which are compatible with trellis codes are considered: maximum-likelihood sequence estimation (MLSE), reduced-state sequence …

Analysis of and techniques for adaptive equalization for underwater acoustic communication
… data-rate communication challenging. Adaptive decision feedback equalization is a common method to compensate for distortions introduced by the underwater acoustic channel. Limited work has been done thus far to introduce the physics of the underwater channel into improving and better …

Optical receiver techniques for integrated photonic links
… new ways to implement double-data-rate and decision-feedback-equalization operation. The receivers are fabricated as part of an integrated photonic test platform, and the measurements are detailed. This work presents the first-ever monolithically-integrated optical receiver with …

Model predictive control equalization for high-speed IO links
… discontinuities, the data rate is being limited. Equalization schemes have been developed to cope with these problems. These equalizers compensate the loss of transmission mediums, equalize for reflections and extend the channel's maximum data rate. In this work, we formulate a new, nonlinear and …

A super-nyquist architecture for rateless underwater acoustic communication
… among them dithered repetition coding, adaptive decision feedback equalization (DFE), and multiple-input multiple-output (MIMO) communication. We present a complete block diagram for the transmitter and receiver architecture for the SNQ scheme. We prove the sufficiency of the architecture for …

High Capacity VCSEL Array Based Optical Wireless Links
… using On-Off Keying (OOK) modulation and Decision Feedback Equalization (DFE) over a 3 m link, using a Silicon Photomultiplier (SiPM) receiver. The novel multibeam VCSEL array based-OWC transmitter is demonstrated to enhance the channel capacity Three 20 cm × 20 cm square cells are shown …

Resource allocation for CDMA downlink to achieve maximum throughput
… versus single carrier systems are analyzed with decision feedback equalization. In CDMA systems, for a fixed bandwidth allocation, the transmission rate can be altered by varying one or more of the coding, interleaving, modulation and spreading block parameters. In the downlink of DS-CDMA …

Αποδοτικές τεχνικές εκτίμησης – ισοστάθμισης γενικευμένων ασύρματων καναλιών πολλαπλών εισόδων – πολλαπλών εξόδων
Τα συστήματα πολλαπλών κεραιών στον πομπό και στο δέκτη (MIMO) αποτελούν βασικά μέτωπα ανάπτυξης των ασύρματων επικοινωνιών. Ωστόσο, η εφαρμογή της τεχνολογίας MIMO στα κινητά δίκτυα επικοινωνιών αντιμετωπίζει το πρακτικό πρόβλημα της ενσωμάτωσης πολλαπλών κεραιών σε μικρά κινητά τερματικά. Με …
