1. Generation and Transmission of Optical Solitons at Ultrahigh Bit Rates
Abstract : This thesis deals with the generation and transmission of optical solitons in ultrahigh-speed fiber-optic communication systems. For optical soliton pulses the fiber dispersion and nonlinearity can under certain circumstances cancel each other, thus allowing the solitons to remain undistorted over long distances. READ MORE

2. On Spectrally Efficient Continuous Phase Modulation
Abstract : Spectrally efficient partial response continuous phase modulation (CPM)for wireless links is considered. Continuous phase modulation defines constantenvelope phase codes, which are advantageous when using non-linear amplifiers. READ MORE

3. On a laser anglemeter for mobile robot navigation
Abstract : A laser anglemeter for use in a navigation system for mobile robots has been developed. The anglemeter measures heading angles to beacons made of vertical stripes of retroreflective tape. The anglemeter uses an- optical system with a rotating mirror. READ MORE

4. Generalized APP Detection for Communication over Unknown Time-Dispersive Waveform Channels
Abstract : The principle of transmitting time-equidistant pulses to carry discrete information is fundamental. When the pulses overlap, intersymbol interference occurs. Maximum-likelihood sequence detection of such signals observed in additive white Gaussian noise (AWGN) was known in the early 1970s. READ MORE

5. Digital block transmission and time-of-flight estimation : receiver design and performance analysis
Abstract : This thesis is concerned with signal processing aspects of digital block transmission and time-of-flight estimation. Receivers are derived and analysed based on the assumption that the received signals have been corrupted with additive Gaussian noise and linear distortion. READ MORE
