Families of sequences with optimal Hamming-correlation properties

IEEE Transactions on Information Theory, 1974
Let \(x\) be a maximal length sequence, of length \(p^n-1\), \(p\) prime, of elements from \(\mathrm{GF}(p)\). For any \(k\), \(1\leq k\leq n\), take any \(k\) length vector of elements from \(\mathrm{GF}(p)\) and add it modulo \(p\) to each consecutive \(k\) bits of \(x\), including end around sets. The resulting \(p^2 -1\) \(k\)-length vectors over \(

On the average hamming correlation of frequency-hopping sequence sets with good maximum hamming correlation

Proceedings of the Fifth International Workshop on Signal Design and Its Applications in Communications, 2011
For frequency-hopping spread spectrum (FHSS) communication systems, the average Hamming correlation (AHC) among frequency-hopping sequences (FHSs) is an important performance measure, as well as the maximum Hamming correlation (MHC). In this paper, we study FHS sets with optimal AHC and good MHC. First, we analyze the AHC of known FHS sets with optimal

Hamming distance correlation for q-ary constant weight codes

2010 International Symposium On Information Theory & Its Applications, 2010
We proposed a method for q-ary constant weight codes from the cyclic difference set by generalization of the method in binary case proposed by N. Li, X. Zeng and L. Hu in 2008. It was shown that two sets of constant weight codes over Z 5 with length 21 from the (21, 5, l)-planar (cyclic) difference set and constant weight codes over G F (8) with ...

The Average Hamming Correlation for the Cubic Polynomial Hopping Sequences

2008 International Wireless Communications and Mobile Computing Conference, 2008
The average Hamming correlation is an important performance indicator of the frequency hopping sequences. In this paper, the lower bound on the average Hamming correlation for frequency hopping sequences with respect to the size q of the frequency slot set, the sequence length L, the family size M, the average Hamming autocorrelation Aa and the average
