Secure Codes with List Decoding
Yujie Gu, Ilya Vorobyev, Ying Miao
In this paper we consider combinatorial secure codes in traitor tracing for protecting copyright of multimedia content. First, we introduce a new notion of secure codes with list d…
Ziv-Zakai Bound for DOAs Estimation
Zongyu Zhang, Zhiguo Shi, Yujie Gu
Lower bounds on the mean square error (MSE) play an important role in evaluating the direction-of-arrival (DOA) estimation performance. Among numerous bounds for DOA estimation, th…
Bounds on the Capacity of PIR over Graphs
Bar Sadeh, Yujie Gu, Itzhak Tamo
In the private information retrieval (PIR) problem, a user wants to retrieve a file from a database without revealing any information about the desired file's identity to the serve…
On Compressed Sensing Matrices Breaking the Square-Root Bottleneck
Shohei Satake, Yujie Gu
Compressed sensing is a celebrated framework in signal processing and has many practical applications. One of challenging problems in compressed sensing is to construct determinist…
Strongly separable matrices for nonadaptive combinatorial group testing
Jinping Fan, Hung-Lin Fu, Yujie Gu +2
In nonadaptive combinatorial group testing (CGT), it is desirable to identify a small set of up to defectives from a large population of items with as few tests (i.e. large…
On the Non-Adaptive Zero-Error Capacity of the Discrete Memoryless Two-Way Channel
Yujie Gu, Ofer Shayevitz
We study the problem of communicating over a discrete memoryless two-way channel using non-adaptive schemes, under a zero probability of error criterion. We derive single-letter in…
On -parent-identifying set systems of block size
Yujie Gu, Shohei Satake
Parent-identifying set system is a kind of combinatorial structures with applications to broadcast encryption. In this paper we investigate the maximum number of blocks …
Probabilistic Existence Results for Parent-Identifying Schemes
Yujie Gu, Minquan Cheng, Grigory Kabatiansky +1
Parent-identifying schemes provide a way to identify causes from effects for some information systems such as digital fingerprinting and group testing. In this paper, we consider c…
Signature codes for weighted binary adder channel and multimedia fingerprinting
Jinping Fan, Yujie Gu, Masahiro Hachimori +1
In this paper, we study the signature codes for weighted binary adder channel (WbAC) and collusion-resistant multimedia fingerprinting. Let denote the maximum cardinality…
Bounds on Traceability Schemes
Yujie Gu, Ying Miao
The Stinson-Wei traceability scheme (known as traceability scheme) was proposed for broadcast encryption as a generalization of the Chor-Fiat-Naor traceability scheme (known as tra…
