    Summary form only given. Complementary sequence pairs were introduced by Golay in 1951, and have found application to many areas of signal processing and communications, such as to radar, tomography, and to power control for multicarrier wireless transmission. They are attractive because the sum of their aperiodic autocorrelations has zero sidelobes, and therefore the sum of their Fourier power sp... View full abstract»

    Summary form only given. Distributed source coding (DSC) considers the problem of separate compression and joint decompression of multiple correlated sources. Berger and Tung first introduced the multiterminal (MT) source coding problem and studied the region of all possible encoder rate tuples such that the sources are reconstructed under distortion constraints. One can loosely view MT source cod... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (44 KB) | HTML iconHTML

    For the past decades, maximal linear recursive sequences (m-sequences) have been studied by many researchers. M-sequences have ideal autocorrelation property, which is useful in various wireless communication systems. Some m-sequences have low cross-correlation values which is essential property for extensive application of code division multiple access (CDMA) of spread spectrum communication syst...

  • Bridge between signal processing and information theory

    Publication Year: 2011, Page(s): 5
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (42 KB)

    Minimum mean square error (MMSE) is a common measure used in signal processing. On the other hand, mutual information is a common measure used in information theory. A connection between MMSE and mutual information has been revealed recently, which establishes an interesting MMSE-I relationship. In this talk, we will discuss the applications of the MMSE-I relationship in communication systems. In ... View full abstract»

  • About computation of the linear complexity of generalized cyclotomic sequences with period pq

    Publication Year: 2011, Page(s):9 - 12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (179 KB) | HTML iconHTML

    We propose a computation method for linear complexity of series of generalized cyclotomic sequences with period pq. This method is based on using the polynomial of the classical cyclotomic sequence, this allows to obtain well-known results and also new results. We found the linear complexity of Whiteman generalized cyclotomic sequences based on cyclotomic classes of order six. View full abstract»

    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (181 KB) | HTML iconHTML

    For cyclic codes we proposed a new lower bound of minimum distance by discrete Fourier transform (DFT). In this paper, we will show relationships between the proposed bound and the shift bound by numerical experiments. Moreover, the computational complexity of proposed lower bound is compared with the shift bound. View full abstract»

    Binary sequences with low aperiodic autocorrelation function sidelobes, such as Barker, quasi-Barker, and minimum peak sidelobe sequences have found extensive applications in radar and communications systems. However, there is no systematic method to construct such desirable binary sequences except the use of time consuming and costly exhaustive computer search. In this paper, an upper bound on th...

    In this present paper, we give results that a decrease of the control parameter in the logistic map over integers causes to disappear several loops which have specified periods. We derive the theoretical lower bound of the control parameter for a potential of existing the loop with an odd period on the logistic map over integers. View full abstract»

    The present paper introduces a new approach to the construction of a sequence set with a zero-correlation zone (ZCZ). The proposed sequence construction generates a ZCZ sequence set from a perfect sequence pair or a single perfect sequence. The member size of the proposed sequence set approaches the theoretical bound. The proposed sequence set consists of Lg subsets, where a Hadamard ma... View full abstract»

    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (146 KB) | HTML iconHTML

    A new construction was proposed to design almost optimal sequence set with zero correlation zone(ZCZ). Based on the interleaved technique and recursive algorithm, a new ZCZ sequence set can be generated from an arbitrary perfect sequence, the length of which is longer than 4. And the ZCZ width and length of the new sequence can also be extended by recursive operation. The new sequence set can appr... View full abstract»

  • Zero-cross-correlation properties of asymmetric ZCZ sequence sets

    Publication Year: 2011, Page(s):32 - 35
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (169 KB) | HTML iconHTML

    The present paper proposes a new formula for the zero-cross-correlation zone length between sequences belonging to different sequence subsets in asymmetric zero-correlation zone (ZCZ) sequence sets. An asymmetric ZCZ sequence set is composed of multiple sequence subsets, and the cross-correlation function between sequences that belong to different subsets gives an extremely large zero-cross-correl...

    Zero correlation zone (ZCZ) sequence sets are aimed for possible applications in the quasi-synchronous code-division multiple access (QS-CDMA) communication systems. In this paper, we first discuss the relationship between the upper bound on the zone length and the upper bound on the set size, which are both derived from the bound given by Tang, Fan and Matsufuji. Next, we show that several known ... View full abstract»

  • Zero partial-period correlation zone sequence sets for MIMO channel estimation

    Publication Year: 2011, Page(s):40 - 43
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (162 KB) | HTML iconHTML

    In this paper we propose zero partial-period correlation zone (ZPCZ) sequences which may be considered as a generalized version of conventional zero-correlation zone (ZCZ) sequences. We present their basic properties and apply them to channel estimation. When they are employed as training sequences for multiple-input multiple-output (MIMO) channel estimation, the mean-square error (MSE) of the min... View full abstract»
