Today's communication systems typically use high resolution analog-to-digital converters (ADCs). However, considering future communication systems with data rates in the order of 100 Gbit/s the ADC power consumption becomes a major factor due to the high sampling rates. A promising alternative are receivers based on 1-bit quantization and oversampling w.r.t. the signal bandwidth. Such an approach requires a redesign of modulation, receiver synchronization, and demapping. A zero crossing modulation is a natural choice as the information needs to be carried in the zero crossing time instants. The present paper provides an overview on zero crossing modulation, achievable rates, sequence mapping and demapping, 1-bit based channel parameter estimation, and continuous phase modulation as an alternative zero crossing modulation scheme.

“…Oversampling with respect to the temporal duration of a transmit symbol is used to compensate for the loss in terms of achievable rate. This receive processing approach is considered in combination with continuous phase modulation (CPM) as studied before in [1], [2]. CPM signals are spectral efficient, having smooth phase transitions and constant envelope [3], [4], which allows for energy efficient power amplifiers.…”

A channel with continuous phase modulation and 1bit ADC with oversampling is considered. Due to oversampling, higher-order modulations yield a higher achievable rate and this work presents a method to approach this with sophisticated coding. A tailored bit mapping is proposed where two bits can be detected reliably at high SNR and only the third bit suffers from an error floor. With this, a convolutional code is only applied to the third bit. Our experiments with a turbo receiver show that the proposed method corresponds to a lower BER in comparison to the case of conventional channel coding.

“…The same idea is considered for CPM with 1-bit quantization and oversampling at the receiver in [19], where it is shown how oversampling increases the achievable rate. Later, more practical approaches were proposed in [20], where the intermediate frequency and the waveform is considered in a geometrical analysis of the phase transitions.…”

First of all I would like to thank my advisor Prof. Lukas Landau for giving me the opportunity to work on this thesis. With his continuous support and motivation, he has shown his passion towards lecturing and assisting students. More than that, he presents a friendly behavior, striving for meaningful interactions with students and fellow professors. For all above said and for treating with all regard my own ideas onto this research topic, he deserves my sincere gratitude. I also want to express my gratitude to the professors from CETUC for sharing experience and knowledge during the courses lectures. For this reason, it is worth to mention the professors Raimundo Sampaio Neto, José Mauro Pedro Fortes and, especially, Rodrigo Caiado de Lamare, who has contributed directly and indirectly to this work, with mentorship and paper review. Furthermore, I want to thank IMBEL for enabling the completion of this thesis by allowing the flexibility of the working hours during this period. More specifically, I want to thank Colonel Marcus Vinícius dos Santos Fernandes for this support, understanding the importance of the master's degree for the career of an engineer.
