Galois Hulls of Generalized Roth-Lempel Codes and Their Applications to EAQECCs
Xuefei Wu, Qi Liu, Yingchun Chen +1
The dimension of a Galois hull is an important parameter in the construction of entanglement-assisted quantum error-correcting codes. In this paper, we study generalized Roth-Lempe…

On Twisted Roth-Lempel Codes
Huiyue Lei, Haojie Gu, Jun Zhang +1
In 1989, Roth and Lempel constructed a well-known family of non-Reed-Solomon maximum distance separable (MDS) codes. For decades, this family of codes has attracted extensive resea…

Large Sets of Quasi-Complementary Sequences From Polynomials over Finite Fields and Gaussian Sums
Ziling Heng, Peng Wang, Chunlei Xie +1
Perfect complementary sequence sets (PCSSs) are widely used in multi-carrier code-division multiple-access (MC-CDMA) communication systems. However, the set size of a PCSS is upper…
