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…

Impact of Low-Resolution ADC on DOA Estimation Performance for Massive MIMO Receive Array

Baihua Shi, Nuo Chen, Xicheng Zhu +4

In this paper, we present a new scenario of direction of arrival (DOA) estimation using massive multiple-input multiple-output (MIMO) receive array with low-resolution analog-to-di…

Schedule Sequence Design for Broadcast in Multi-channel Ad Hoc Networks

Fang Liu, Kenneth W. Shum, Yijin Zhang +1

We consider a single-hop ad hoc network in which each node aims to broadcast packets to its neighboring nodes by using multiple slotted, TDD collision channels. There is no coopera…

Multichannel Conflict-Avoiding Codes of Weights Three and Four

Yuan-Hsun Lo, Kenneth W. Shum, Wing Shing Wong +1

Conflict-avoiding codes (CACs) were introduced by Levenshtein as a single-channel transmission scheme for a multiple-access collision channel without feedback. When the number of s…

Age-of-Information-based Scheduling in Multiuser Uplinks with Stochastic Arrivals: A POMDP Approach

Aoyu Gong, Tong Zhang, He Chen +1

In this paper, we consider a multiuser uplink status update system, where a monitor aims to timely collect randomly generated status updates from multiple end nodes through a share…
