Digital pre-compensation for faulty D/A converters : the "missing pixel" problem
… possible to compensate for the dropped sample by pre-processing the digital signal, thereby reducing the analog reconstruction error. We develop three such compensation strategies in this thesis. The first strategy uses constrained minimization to calculate the optimal finite-length compensation …

Pre-compensation of nonlinear distortion of a silicon microring modulator in short reach systems
… modulation efficiency, and is potentially preferable for short reach transmission systems. This research focuses on the implementation of an MRM in a high-speed short reach communication system. One issue with Si-MRMs is the nonlinear electrical-to-optical modulation dynamics. This work …

Channel Related Optimization of Wireless Communication Systems
… to resulting bit error rate. An analytical expression for the bit error rate on Rayleigh fading channels when interchannel interference, ICI, caused by channel changes during a symbol and energy loss due to the cyclic prefix are regarded. This expression is used to optimize the number of …

The development of high power fibre chirped pulse amplification systems
… efficiency, ytterbium (Yb)-doped silica fiber represents an attractive medium for the generation and amplification of ultrashort optical pulses. Research interest in Yb-doped fiber chirped pulse amplifier (CPA) systems first appeared in the late 1990s. However, the potential advantages and …

Digital equalization techniques for the compensation of nonlinear impairments in long-haul coherent optical communication systems
… direct-detection receivers. A precursor to this development was the introduction in the early 2000 of differential phase shift keying in conjunction with a direct-detection using a delay interferometer. The advantages of latter modulation formats were the following: a) it …
