Adaptive Kalman receiver for OFDM systems with transmit diversity in mobile wireless channels
(Walter De Gruyter GMBH, 2004-12)
A new joint channel tracking and symbol detection scheme is proposed in this paper for pilot symbol assisted transmit diversity OFDM systems by exploiting the correlation of the adjacent subchannels. Modelling the channel ...
A novel method to represent the speech signals by using language and speaker independent predefined functions sets
(IEEE, 2004)
In this paper a new modeling method of speech signals is introduced. The proposed method is based on the generation of the so-called Predefined Signature S={s(R)(t)} and Envelope Function E = {e(K)(t)} Sets (PSEFS). These ...
Error propagation through generalized high dimensional model representation for data partitioning
(Wiley-V C H Verlag GMBH, 2004)
In many circumstances the explicit form of a multivariate function is not known; rather a finite number of data is listed from some physical experiments. In such cases a function can be constructed only by imposing some ...
Immitance data modelling via linear interpolation techniques: a classical circuit theory approach
(Wiley-Blackwell, 2004-11)
With the advancement of the manufacturing technologies to produce new generation analog/digital communication systems, immitance data modelling has gained renewed importance in the literature. Specifically, models are ...
Forward-viewing CMUT arrays for medical Imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2004-07)
This paper reports the design and testing of forward-viewing annular arrays fabricated using capacitive micromachined ultrasonic transducer (CMUT) technology. Recent research studies have shown that CMUTs have broad frequency ...
A computer-aided design technique for lossless matching networks with mixed, lumped and distributed elements
(Elsevier GMBH, 2004)
A computer-aided method for the design of lossless broadband matching networks with lumped elements and commensurate transmission lines is presented. ne method is based on combining the simplifield real frequency technique ...
Iterative channel estimation approach for space-time/frequency coded OFDM systems with transmitter diversity
(Assoc Elettrotecnica Ed Elettronica Italiana, 2004-06)
Focusing on transmit diversity orthogonal frequency division multiplexing (OFDM) transmission through frequency selective channels, this paper pursues novel iterative channel estimation approaches for both space-frequency ...
Range sensing with a Scheimpflug camera and a CMOS sensor/processor chip
(IEEE-INST Electrical Electronics Engineers Inc, 2004-02)
An image-based range-sensing technique is presented. The technique is originally considered for highway collision avoidance applications, but its generality makes it suitable for application in robotics, manufacturing, and ...
Influence of the velocity on the energy patterns of moving scatterers
(Taylor & Francis, 2004)
Parallel to the developments in the communication through space vehicles achieved during the last two decades, the scattering problems connected with moving objects became more and more important from both theoretical and ...
3-B nesne bilgilerinin vektor nicemleme yöntemleri ile sıkıştırılması
(IEEE, 2004-10-25)
Bu çalışmanın amacı, bağlanırlık kodlaması için gerçeklenmiş [I]'deki algoritmayı bazı yenilikler ile uygulamak ve koordinat sıkıştırması için 3-B (3 Boyutlu) nesne gösterimleri alanında kullanımı kısıtlı olan kayıplı bir ...
