The application of independent component analysis (ICA) algorithm can achieve a real time blind signal separation (BSS) if it is physically implemented using hardware devices. However, due principally to both of the limited size and of the microelectronics technology of the used hardware devices, many practical problem can be encountered to reach the real(More)
IEEE 802.11ad is the new Wi-Fi standard operating at 60 GHz. This paper investigate the performance of specified modulation and coding schemes in additive white Gaussian noise channel and realistic 60 GHz band multipath fading channel. Three 802.11 ad physical layers, namely orthogonal frequency division multiplex physical layer, Single Carrier and Low(More)
Radio Frequency Identification (RFID) is a popular automatic identification and an emerging wireless technology with highly promising applications. In an RFID system, the anti-collision algorithm is one of the primary mechanisms to address the issue of multi-object identification. This paper focused on a detailed study of the ALOHA anti-collision problem(More)
For Radio Frequency Identification (RFID) system, this paper presents an anti collision circuit design for fast of multi tags identification system. Principally, the authors use the Blind Signal Separation (BSS) method by the Independent Component Analysis (ICA) algorithm based computation of anti-collision circuit for speedily extracting the hidden factor(More)
In this paper, the authors targeted multiple access protocols to analyze the problem of collision and collision avoidance in RFID systems. By considering user terminals as tags and access point as reader, the authors efficiently modelled the wireless communication channel by considering the capture effect. Otherwise, if the capture effect is not considered,(More)
The purpose of this paper is the establishment of the adequate choice of trial functions used in the transverse resonance method for modeling asymmetric coupled microstrip structures for C- and pi-mode in full-wave domain. So, two kinds of the set of cosine trial functions are used (one takes into account the edge metallic effects and other does not take(More)
This works deals with powerful approach treating the design of radiofrequency and microwave lowpass filters. A very compact topology is proposed by folding a conventional stepped impedance configuration whereas introducing an end gap coupling improving thus the filter selectivity. The lowpass filter is designed at 1 GHz cutoff frequency and implemented on(More)
This paper introduces a relevant concept of energy harvesting for passive UHF radio frequency identification (RFID) relying on the exploitation of the power carried by the third harmonic signal generated by the RFID chip. The idea consists on the use of the sole third harmonic energy to power up an associated sensor to the RFID tag. The proposed concept is(More)
