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…
Secure Hybrid Digital and Analog Precoder for mmWave Systems with low-resolution DACs and finite-quantized phase shifters
Ling Xu, Feng Shu, Guiyang Xia +3
Millimeter wave (mmWave) communication has been regarded as one of the most promising technologies for the future generation wireless networks because of its advantages of providin…
