Generalized Hamming weights of three classes of linear codes
Gaopeng Jian
The generalized Hamming weights of a linear code have been extensively studied since Wei first use them to characterize the cryptography performance of a linear code over the wire-…
Two-weight and three-weight linear codes based on Weil sums
Gaopeng Jian
Linear codes with few weights have applications in secret sharing, authentication codes, association schemes and strongly regular graphs. In this paper, several classes of two-weig…
Nonexistence of Generalized Bent Functions From to
Haiying Liu, Keqin Feng, Rongquan Feng
Several nonexistence results on generalized bent functions presented by using some knowledge on cyclotomic number fields and their imaginary quadrat…
On the Solvability of 3s/nt Sum-Network---A Region Decomposition and Weak Decentralized Code Method
Wentu Song, Kai Cai, Chau Yuen +1
We study the network coding problem of sum-networks with 3 sources and n terminals (3s/nt sum-network), for an arbitrary positive integer n, and derive a sufficient and necessary c…
Network Coding for st Sum-Networks
Wentu Song, Chau Yuen, Kai Cai +1
A sum-network is a directed acyclic network where each source independently generates one symbol from a given field and each terminal wants to receive the sum over $…
Error Correction for Cooperative Data Exchange
Wentu Song, Xiumin Wang, Chau Yuen +2
This paper considers the problem of error correction for a cooperative data exchange (CDE) system, where some clients are compromised or failed and send false messages. Assuming ea…
Bounds on and Constructions of Unit Time-Phase Signal Sets
Cunsheng Ding, Keqin Feng, Rongquan Feng +1
Digital signals are complex-valued functions on . Signal sets with certain properties are required in various communication systems. Traditional signal sets consider only the…
On the Construction of Finite Oscillator Dictionary
Rongquan Feng, Zhenhua Gu, Zilong Wang +2
A finite oscillator dictionary which has important applications in sequences designs and the compressive sensing was introduced by Gurevich, Hadani and Sochen. In this paper, we fi…
A Generalized Construction of OFDM M-QAM Sequences With Low Peak-to-Average Power Ratio
Zilong Wang, Guang Gong, Rongquan Feng
A construction of -QAM sequences is given and an upper bound of the peak-to-mean envelope power ratio (PMEPR) is determined. Some former works can be viewed as special case…
On the Solvability of 2-pair Unicast Networks --- A Cut-based Characterization
K. Cai, K. B. Letaief, P. Fan +1
In this paper, we propose a subnetwork decomposition/combination approach to investigate the single rate -pair unicast problem. It is shown that the solvability of a -pair un…
Encoding Complexity of Network Coding with Two Simple Multicast Sessions
Wentu Song, Kai Cai, Rongquan Feng +1
The encoding complexity of network coding for single multicast networks has been intensively studied from several aspects: e.g., the time complexity, the required number of encodin…
Cross-correlation properties of cyclotomic sequences
Kai Cai, Rongquan Feng, Zhiming Zheng
Sequences with good correlation properties are widely used in engineering applications, especially in the area of communications. Among the known sequences, cyclotomic families hav…
