Multichannel Conflict-Avoiding Codes for Expanded Scenarios
Tsai-Lien Wong, Kangkang Xu, Yuan-Hsun Lo +2
A conflict-avoiding code (CAC) of length L and weight w is used for deterministic multiple-access without feedback. When the number of simultaneous active users is less than or equ…

Multiset Combinatorial Gray Codes with Application to Proximity Sensor Networks
Chung Shue Chen, Wing Shing Wong, Yuan-Hsun Lo +1
We investigate coding schemes that map source symbols into multisets of an alphabet set. Such a formulation of source coding is an alternative approach to the traditional framework…

Optimal Constant-Weight and Mixed-Weight Conflict-Avoiding Codes
Yuan-Hsun Lo, Tsai-Lien Wong, Kangkang Xu +1
A conflict-avoiding code (CAC) is a deterministic transmission scheme for asynchronous multiple access without feedback. When the number of simultaneously active users is less than…
