QCTP: A Novel Pre-Coding Approach for PAPR Reduction in IM/DD Systems

open access: yesIEEE Access
Orthogonal frequency division multiplexing (OFDM) is critical for high-speed visible light communication (VLC) transmission; however, it suffers from a high peak-to-average power ratio (PAPR) problem.

Video coding optimization techniques

open access: yes
Οι τεχνικές κωδικοποίησης βίντεο αποδεικνύονται ιδιαιτέρως σημαντικές τα τελευταία χρόνια, λόγω της δραματικής αύξησης της χρήσης βίντεο παγκοσμίως, που απαιτεί διαρκώς υψηλότερη ποιότητα εικόνας, με όσο το δυνατό χαμηλότερη ροή δεδομένων και μεγέθη αποθηκευτικού χώρου.

Trellis coded modulation techniques [PDF]

open access: yes
The subject of this thesis is an investigation of various trellis coded modulation (TCM) techniques that have potential for out-performing conventional methods. The primary advantage of TCM over modulation schemes employing traditional error-correction coding is the ability to achieve increased power efficiency without the normal expansion of bandwidth
