Continuous Phase Modulation With 1-Bit Quantization and Oversampling Using Iterative Detection and Decoding
Rodrigo R. M. de Alencar, Lukas T. N. Landau, Rodrigo C. de Lamare
A channel with continuous phase modulation and 1-bit ADC with oversampling is considered. Due to oversampling, higher-order modulations yield a higher achievable rate and this work…
Zero Crossing Modulation for Communication with Temporally Oversampled 1-Bit Quantization
Gerhard Fettweis, Meik Dörpinghaus, Sandra Bender +3
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 1…
Zero-Crossing Precoding With Maximum Distance to the Decision Threshold for Channels With 1-Bit Quantization and Oversampling
Diana M. V. Melo, Lukas T. N. Landau, Rodrigo C. de Lamare
Low-resolution devices are promising for systems that demand low energy consumption and low complexity as required in IoT systems. In this study, we propose a novel waveform for ba…
Continuous Phase Modulation With Faster-than-Nyquist Signaling for Channels With 1-bit Quantization and Oversampling at the Receiver
Rodrigo R. M. de Alencar, Lukas T. N. Landau
Continuous phase modulation (CPM) with 1-bit quantization at the receiver is promising in terms of energy and spectral efficiency. In this study, CPM waveforms with symbol duration…
Investigation of Channel Estimation Techniques with 1-bit Quantization and Oversampling for Multiple-Antenna Systems
Z. Shao, L. Landau, R. C. de Lamare
Large-scale multiple-antenna systems have been identified as a promising technology for the next generation of wireless systems. However, by scaling up the number of receive antenn…
Optimal Precoding for Multiuser MIMO Systems With Phase Quantization and PSK Modulation via Branch-and-Bound
Erico S. P. Lopes, Lukas T. N. Landau
