On Zero Error Capacity of Nearest Neighbor Error Channels with Multilevel Alphabet
Takafumi Nakano, Tadashi Wadayama
This paper studies the zero error capacity of the Nearest Neighbor Error (NNE) channels with a multilevel alphabet. In the NNE channels, a transmitted symbol is a -tuple of elem…

Analysis of Breakdown Probability of Wireless Sensor Networks with Unreliable Relay Nodes
Takayuki Nozaki, Takafumi Nakano, Tadashi Wadayama
In the present paper, we derive an upper bound of the average network breakdown probability of packet networks with unreliable relay nodes. We here assume that relay nodes get inde…
