Frequency Hopping Sequences with Optimal Auto- and Cross-Correlation Properties and Related Codes
Frequency-hopping (FH) spread-spectrum techniques employ sequences with Hamming correlation properties meeting suitable criteria. In this correspondence novel families of FH sequences having optimal autoand cross-correlation properties with respect to the well-known Lempel-Greenberger bound are developed through combinatorial product type constructions. This provides us new optimal families of ...
متن کاملFrequency hopping sequences with optimal partial Hamming correlation
Frequency hopping sequences (FHSs) with favorable partial Hamming correlation properties have important applications in many synchronization and multiple-access systems. In this paper, we investigate constructions of FHSs and FHS sets with optimal partial Hamming correlation. We first establish a correspondence between FHS sets with optimal partial Hamming correlation and multiple partition-typ...
متن کاملOn the Hamming Auto- and Cross-correlation Functions of a Class of Frequency Hopping Sequences of Length $ p^{n} $
In this paper, a new class of frequency hopping sequences (FHSs) of length p is constructed by using Ding-Helleseth generalized cyclotomic classes of order 2, of which the Hamming autoand crosscorrelation functions are investigated (for the Hamming cross-correlation, only the case p ≡ 3 (mod 4) is considered). It is shown that the set of the constructed FHSs is optimal with respect to the avera...
متن کاملChaotic frequency hopping sequences
This letter describes a novel family of frequency hopping sequences generated by chaotic systems. The sequences give a uniform spread over the entire frequency bandwidth. In addition to having good Hamming correlation properties, they possess ideal linear span. The sequences produce almost as good performance as random hopping patterns when used in frequency hopping code-division multiple-acces...
متن کاملFurther combinatorial constructions for optimal frequency-hopping sequences
Frequency-hopping multiple-access (FHMA) spread-spectrum communication systems employing multiple frequency shift keying as data modulation technique were investigated by Fuji-Hara, Miao and Mishima [R. Fuji-Hara, Y. Miao, M. Mishima, Optimal frequency hopping sequences: A combinatorial approach, IEEE Trans. Inform. Theory 50 (2004) 2408–2420] from a combinatorial approach, where a corresponden...
