Product Construction of Affine Codes
Yeow Meng Chee, Han Mao Kiah, Punarbasu Purkayastha +1
Binary matrix codes with restricted row and column weights are a desirable method of coded modulation for power line communication. In this work, we construct such matrix codes tha…
Importance of Symbol Equity in Coded Modulation for Power Line Communications
Yeow Meng Chee, Han Mao Kiah, Punarbasu Purkayastha +1
The use of multiple frequency shift keying modulation with permutation codes addresses the problem of permanent narrowband noise disturbance in a power line communications system.…
Cross-Bifix-Free Codes Within a Constant Factor of Optimality
Yeow Meng Chee, Han Mao Kiah, Punarbasu Purkayastha +1
A cross-bifix-free code is a set of words in which no prefix of any length of any word is the suffix of any word in the set. Cross-bifix-free codes arise in the study of distribute…
Estimates on the Size of Symbol Weight Codes
Yeow Meng Chee, Han Mao Kiah, Punarbasu Purkayastha
The study of codes for powerlines communication has garnered much interest over the past decade. Various types of codes such as permutation codes, frequency permutation arrays, and…
Near MDS poset codes and distributions
Alexander Barg, Punarbasu Purkayastha
We study -ary codes with distance defined by a partial order of the coordinates of the codewords. Maximum Distance Separable (MDS) codes in the poset metric have been studied in…
Bounds on ordered codes and orthogonal arrays
Alexander Barg, Punarbasu Purkayastha
We derive new estimates of the size of codes and orthogonal arrays in the ordered Hamming space (the Niederreiter-Rosenbloom-Tsfasman space). We also show that the eigenvalues of t…
