On reconstructable ask-sequences for receivers employing 1-Bit quantization and oversampling

Multigigabit communications based on 1-Bit quantization at the receiver benefit from relaxed power consumption as compared to conventional system designs, especially for short range communications. Utilizing oversampling at the receiver compensates partially the loss in terms of achievable rate brought by the coarse quantization via enabling and exploiting the inherent channel memory. This work proposes methods how to construct ASK-sequences which can be perfectly reconstructed at the receiver. Besides this advantage the proposed sequences are also superior in terms of achievable rate as compared to independent uniformly distributed input signals. Simulation based computations of the achievable rate confirm the theory of the model and the benefit of the oversampling approach.
