Complete Complementary Codes Composed of Perfect Sequences and their Application to Mobile Communications
نویسندگان
چکیده
A complete complementary code composed of 4phase perfect (orthogonal) sequences is shown. The sequences compose a matrix whose cube is a unit matrix. A method is also discussed, which has been proposed by Suehiro, et.al. for increasing the efficiency of the wireless frequency usage. The method uses a pilot signal for measuring the multipath property as a complex number for each timeslot. The data transmission signals transmitted together with the pilot signal using the same frequency and time without interference. The signals with zero-autocorrelation zone and zerocrosscorrelation zone (ZCZ signals) are made based on the complete complementary code and used for above method.

An algebraic approach to generate super-set of perfect complementary codes for interference-free CDMA
This paper introduces an algebraic approach to generate the super-set of perfect complementary (PC) codes suitable for new generation CDMA applications, characterized by isotropic multiple access interference (MAI) free and multipath interference (MI) free properties. The code design methodology proposed in this paper takes into account major impairing factors existing in real applications, suc...
متن کاملHigh Fuzzy Utility Based Frequent Patterns Mining Approach for Mobile Web Services Sequences
Nowadays high fuzzy utility based pattern mining is an emerging topic in data mining. It refers to discover all patterns having a high utility meeting a user-specified minimum high utility threshold. It comprises extracting patterns which are highly accessed in mobile web service sequences. Different from the traditional fuzzy approach, high fuzzy utility mining considers not only counts of mob...
متن کاملDesign of concatenated extended complementary sequences for inter-base station synchronization in WCDMA TDD mode
The Universal Mobile Telecommunications System (UMTS) being specified by the Third Generation Partnership Project (3GPP) and based upon Wideband Code Division Multiple Access (WCDMA) consists of a frequency division duplex (FDD) mode and a time division duplex (TDD) mode. In the UMTS Terrestrial Radio Access (UTRA) TDD mode, system capacity is maximized with base stations (Node B's) in a UTRA T...
متن کاملLinear codes with complementary duals related to the complement of the Higman-Sims graph
In this paper we study codes $C_p(overline{{rm HiS}})$ where $p =3,7, 11$ defined by the 3- 7- and 11-modular representations of the simple sporadic group ${rm HS}$ of Higman and Sims of degree 100. With exception of $p=11$ the codes are those defined by the row span of the adjacency matrix of the complement of the Higman-Sims graph over $GF(3)$ and $GF(7).$ We show that these codes ha...
متن کاملDistinct 8-QAM+ Perfect Arrays
This paper investigates the construction of 8-QAM+ perfect arrays with at least an odd integer in their sizes, and gives the sufficient condition producing distinct 8-QAM+ perfect arrays. For different choices of odd integers in a given size of at least an odd integer, the resultant distinct 8-QAM+perfect arrays have their own sizes. For each choice, the number of the resultant distinct 8-QAM+p...
