Show full item record Abstract This thesis develops and investigates enhanced techniques for carrierless amplitude and phase modulation CAP in optical communication systems. The CAP scheme is studied as the physical layer modulation technique due to its implementation simplicity and versatility, that enables its implementation as a single carrier CAP or multi-carrier technique m-CAP. The effect of timing jitter on the error performance of CAP is first investigated. The investigation indicates that synchronization is a critical requirement for CAP receiver and as a result, a novel low-complexity synchronization algorithm is developed with experimental demonstration for CAP-based visible light communication VLC systems. To further reduce the overall link complexity, a fractionally-spaced equalizer FSE is considered to mitigate the effects of inter-symbol interference ISI and timing jitter. Furthermore, in this thesis, spectrally-efficient index modulation techniques are developed for CAP.

Member feedback about Carrierless amplitude phase modulation: Carrierless amplitude phase modulation. John Cioffi born November 7, is an American electrical engineer, educator and prolific inventor who has made contributions in telecommunication system theory, specifically in coding theory and information theory. Transmission over the single pair requires echo cancellation and adaptive equalizers in order to achieve the maximum range at a specific rate. It conveys two analog message signals, or two digital bit streams, by changing modulating the amplitudes of two carrirrless waves, using the amplitude-shift keying ASK digital modulation scheme or amplitude modulation AM analog modulation scheme. Retrieved 23 June If bit swapping is disabled then this does not happen and the modem needs to retrain in order to adapt to changing line conditions.
