1-bit quantization and oversampling at the receiver: Sequence-based communication
Abstract Receivers based on 1-bit quantization and oversampling with respect to the transmit signal bandwidth enable a lower power consumption and a reduced circuit complexity compared to conventional amplitude quantization. In this work, the achievable rate for systems using such analog-to-digital...

| description | Abstract Receivers based on 1-bit quantization and oversampling with respect to the transmit signal bandwidth enable a lower power consumption and a reduced circuit complexity compared to conventional amplitude quantization. In this work, the achievable rate for systems using such analog-to-digital conversion with different modulation schemes is studied. The achievable rate and the spectral efficiency with respect to a given power containment bandwidth are considered. The proposed sequence-based communication approach outperforms the existing methods known from the literature on noisy channels with 1-bit quantization and oversampling at the receiver. It is demonstrated that the utilization of 1-bit quantization and oversampling can be superior in terms of the spectral efficiency in comparison to conventional amplitude quantization using a flash converter with the same number of comparator operations per time interval. |
