Enhanced 5G PUCCH using Non-Coherent Constellations with Low-Complexity Detection

In the context of coverage enhancement of 5G uplink control channel, we propose a non-coherent signaling based on 2nd-order Reed-Muller constellations that come by design with a low-complexity chirp reconstruction algorithm (ChirpRA). Non-coherent multi-dimensional constellations are known to provide performance gains but often believed to be at the cost of an increased detection complexity. We sh...
