Adaptive Transceiver for Wireless NoC to Enhance Multicast/Unicast Communication Scenarios

Wireless Network-on-Chip (WiNoC) is a viable solution to overcome critical bottlenecks in on-chip communication backbone. However, standard WiNoC approaches are vulnerable to multi-path interference introduced by on-chip physical structures. To overcome such parasitic phenomenon, this paper presents an adaptive digital transceiver, which enhances communication reliability under different wireless channel configurations. Based on a semi-realistic wireless channel model, we investigate the impact of using some channel correction techniques. Experimental results show that our approach significantly improves Bit Error Rate (BER) under different wireless channel configurations. Moreover, our adaptive transceiver allows for wireless communication links to be established in conditions where this would not be possible for standard transceiver architectures. The proposed architecture, designed using a 28-nm FDSOI technology, consumes only 3.27 mW for a data rate of 10 Gbit/s and has a very small area footprint.
