This paper will propose a novel multiple access technology, called OWDM-IDMA (Orthogonal Wavelength-Division Multiplexing-Interleave Division Multiple Access), which is the combination of OWDM (Orthogonal Wavelength-Division Multiplexing) and multiple access schemes IDMA (Interleave Division Multiple Access), in which interleaves are used as the only means(More)
It is proposed to isolate the computation of the scaling matrix in CP tensor decompositions. This has two implications. First, the conditioning of the problem shows up explicitly, and could be controlled via a constraint on the so-called coherences. Second, a performance measure concerning only the factor matrices can be exactly calculated, and does not(More)
Efficiency and adaptivity play a major role in the design of fourth-generation wireless systems (4G). These systems should be efficient in terms of bandwidth and power allocation. Moreover, low complexity transceivers are expected in this type of system. This paper outlines the basic principles of a promising technique for future telecommunications system,(More)
A major drawback of orthogonal frequency division multiplexing interleave division multiple access (OFDM-IDMA) is the high peak to average power ratio (PAPR) of the transmitted signal. In this paper, the basic principle of Orthogonal Wavelength-Division Multiplexing-Interleave Division Multiple Access (OWDM-IDMA) technique is outlines. The PAPR for(More)
Efficiency and adaptivity play a major role in the design of fourth-generation wireless systems (4G). These systems should be efficient in terms of bandwidth and power allocation and will satisfy the users requirement on low power consumption, little interferences with other systems, and high rate transmission. Moreover, low complexity transceivers are(More)
In this paper, we present a canonical polyadic (CP) tensor decomposition isolating the scaling matrix. This has two major implications: (i) the problem conditioning shows up explicitly and could be controlled through a constraint on the so-called coherences and (ii) a performance criterion concerning the factor matrices can be exactly calculated and is more(More)
The phase codes is one of important pulse compression waveform methods. This paper shows and compares the PSLR (Peak Sidelobe Ratio), ISLR (Integrated Sidelobe Ratio) and doppler tolerance for different phase codes. At first, a presentation of the ambiguity function is given, as well as some measures to evaluate it. Then we define some existed phase code(More)
