Optimal Z-complementary Code Set From Generalized Reed-Muller Codes
Palash Sarkar, Sudhan Majhi, Zilong Liu
Z-complementary code set (ZCCS), an extension of perfect complementary codes (CCs), refers to a set of two-dimensional matrices having zero correlation zone properties. ZCCS can be…
New Sets of Optimal Odd-length Binary Z-Complementary Pairs
Avik Ranjan Adhikary, Sudhan Majhi, Zilong Liu +1
A pair of sequences is called a Z-complementary pair (ZCP) if it has zero aperiodic autocorrelation sums (AACSs) for time-shifts within a certain region, called zero correlation zo…
A Direct Construction of Z-Complementary Pairs Using Generalized Boolean Functions
Avik Ranjan Adhikary, Palash Sarkar, Sudhan Majhi
The zero correlation zone (ZCZ) ratio, i.e., the ratio of the width of the ZCZ and the length of the sequence plays a major role in reducing interference in an asynchronous environ…
A Direct Construction of Optimal ZCCS With Maximum Column Sequence PMEPR Two for MC-CDMA System
Palash Sarkar, Sudhan Majhi
Multicarrier code-division multiple-access (MC-CDMA) combines an orthogonal frequency division multiplexing (OFDM) modulation and a code-division multiple-access (CDMA) scheme to e…
New Optimal -Complementary Code Sets from Matrices of Polynomials
Shibsankar Das, Udaya Parampalli, Sudhan Majhi +1
The concept of paraunitary (PU) matrices arose in the early 1990s in the study of multi-rate filter banks. So far, these matrices have found wide applications in cryptography, digi…
A Direct and Generalized Construction of Polyphase Complementary Set with Low PMEPR and High Code-Rate for OFDM System
Palash Sarkar, Sudhan Majhi, Zilong Liu
A major drawback of orthogonal frequency division multiplexing (OFDM) systems is their high peak-to-mean envelope power ratio (PMEPR). The PMEPR problem can be solved by adopting l…
