Practical Low-Weight Codes for Energy-Efficient Bus Encoding
Lorenzo Valentini, Marco Chiani
We consider the transmission of data encoded into binary messages, with the goal of minimizing the Hamming distance, i.e., the number of bit-flips, between consecutive messages. Th…
Exploiting Pilot Mixtures in Coded Random Access
Lorenzo Valentini, Elena Bernardi, Enrico Paolini
The construction of preamble sequences for channel estimation by superposition of orthogonal pilots can improve performance of massive grant-free uplink from machine-type devices.…
Heterogeneous radio access with multiple latency targets
Israel Leyva-Mayorga, Jose Manuel Gimenez-Guzman, Lorenzo Valentini +1
Since the advent of ultra-reliable and low-latency communications (URLLC), the requirements of low-latency applications tend to be completely characterized by a single pre-defined…
Impact of Interference Subtraction on Grant-Free Multiple Access with Massive MIMO
Lorenzo Valentini, Alberto Faedi, Marco Chiani +1
The design of highly scalable multiple access schemes is a main challenge in the evolution towards future massive machine-type communications, where reliability and latency constra…
