A Direct Construction of 2D-CCC with Arbitrary Array Size and Flexible Set Size Using Multivariable Function
Recently, two-dimensional (2D) array codes have been found to have
applications in wireless communication.In this paper, we propose direct
construction of 2D complete complementary codes (2D-CCCs) with arbitrary array
size and flexible set size using multivariable functions (MVF). The
Peak-to-mean envelope power ratio (PMEPR) properties of row and column
sequences of the constructed 2D-CCC arrays are investigated. The proposed
construction generalizes many of the existing state-of-the-art such as Golay
complementary pair (GCP), one-dimensional (1D)-CCC, 2D Golay complementary
array set (2D-GCAS), and 2D-CCC with better parameters compared to the existing
work
Two-Dimensional Z-Complementary Array Quads with Low Column Sequence PMEPRs
In this paper, we first propose a new design strategy of 2D -complementary
array quads (2D-ZCAQs) with feasible array sizes. A 2D-ZCAQ consists of four
distinct unimodular arrays satisfying zero 2D auto-correlation sums for
non-trivial 2D time-shifts within certain zone. Then, we obtain the upper
bounds on the column sequence peak-to-mean envelope power ratio (PMEPR) of the
constructed 2D-ZCAQs by using specific auto-correlation properties of some seed
sequences. The constructed 2D-ZCAQs with bounded column sequence PMEPR can be
used as a potential alternative to 2D Golay complementary array sets for
practical applicationsComment: This work has been presented in 2023 IEEE International Symposium on
