We consider a set of sonar arrays of the same size with an additional constraint that the non-periodic two-dimensional cross-correlation value for any two distinct arrays is limited to either 1 or O. These find applications in various multiuser communication systems such as multiuser radar and sonar systems and/or fiber-optic CDMA networks. We define an optimal pair of sonar arrays ...

Frequency-hopping sequences (FHSs) are used to specify which frequency will be used for transmission at any given time, their properties play important roles in FHMA systems. In this correspondence, new families of FHSs are constructed by using Chinese reminder theorem and C.Ding etal.psilas results. The constructed FHSs family is proved to be optimal and each sequence of the family is ...

We consider a set of sonar arrays of the same size with an additional constraint that the non-periodic two-dimensional cross-correlation value for any two distinct arrays is limited to either 1 or O. These find applications in various multiuser communication systems such as multiuser radar and sonar systems and/or fiber-optic CDMA networks. We define an optimal pair of sonar arrays to be a pair of sonar arrays having an ideal cross-correlation function and having the minimum possible number of columns for a fixed number of rows. We first prove that an optimal pair having a rows can have at most n columns.<<ETX>>
Frequency-hopping sequences (FHSs) are used to specify which frequency will be used for transmission at any given time, their properties play important roles in FHMA systems. In this correspondence, new families of FHSs are constructed by using Chinese reminder theorem and C.Ding etal.psilas results. The constructed FHSs family is proved to be optimal and each sequence of the family is proved to be near optimal.
Code synchronization in direct-sequence spread-spectrum (DSSS) receivers can be divided into the acquisition and the tracking phases. Here we assume that the acquisition is performed with a periodic pseudo-random signal of period N. Acquisition of pseudo-random signals is similar to target detection with a pulse compression radar. The appropriate tool for the description of a pulse compression radars behaviour is the ambiguity function. The present paper describes the code acquisition in DSSS receivers in terms of cross ambiguity functions. Moreover the importance of the merit factor for incoherent acquisition is represented. The signal to interference ratio and an equation giving the optimum matched filter length as a function of the Doppler shift is derived.
Cao et al. characterize one-coincidence frequency-hopping (OC-FH) sequences in terms of perfect Mendelsohn packings (PMP). In this note, we generalize the definition of (v, n, lambda)-PMP to (k, v, n, \lambda)-PMP and provide combinatorial characterizations for sets of k-coincidence frequency-hopping (k-FH) sequences interms of (k, v, n, lambda)-PMP. As a consequence, results on perfect Mendelsohn packings and perfect Mendelsohn designs can be used to construct such sets of k-FH sequences.
An all-lag reference-code correlator generates an all-lag correlation vector at a rate equal to the rate of incoming data samples. Direct implementation of an all-lag reference-code correlator requires N parallel correlators, and the resultant degree of complexity is of the order N/sup 2/, where N is the length of the reference code. This paper derives a recursive form for the all-lag reference-code correlator. It is shown that the proposed recursive all-lag reference-code correlator can be implemented with a complexity approximately equal to that of a single parallel correlator. That is, the degree of complexity of the proposed recursive all-lag reference-code correlator is of the order N. Thus, substantial reduction in the implementation complexity is achieved.
A wideband radar concept with a bandwidth of 3,2 GHz is investigated for automotive application. The wideband direct sequence spread spectrum concept at 24 GHz enables a high resolution with distance cells of less than 0.1 m and an accuracy in the mm-range, a high immunity against interferers and a strong channel separation. A laboratory demonstrator is realised and the feasibility of the concept is shown by way of measured results.
