Study of integration 2.4GHz and 5.8GHz in RFID tag
(Universiti Malaysia Perlis, 2009-10-11)
The most common, though not the only frequencies generally available for RFID use are LF (nominally 132 kHz), HF (13.56 MHz), UHF (860 - 960 MHz) and microwave (2.45 GHz and 5.8 GHz). Wireless LAN systems based on the ...
Spectral amplitude coding OCDMA using and subtraction technique
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and experimental results have been done by comparing Double-Weight (DW) code against the ...
Power-limited spectral amplitude coding OCDMA system using random diagonal code with and without optical amplifiers
(Institute of Electrical and Electronics Engineering (IEEE), 2008)
A new code structure for spectral amplitude coding in optical code division multiple access (OCDMA) systems called Random Diagonal (RD) code is proposed. RD code is constructed using code level and data level. One of the ...
New design of spectral amplitude coding in OCDMA with zero cross-correlation
(Elsevier B.V. (Imprint: NORTH-HOLLAND), 2009-07)
A zero cross-correlation (ZCC) code is proposed to reduce the impact of system impairment and multiple access interference (MAI) in spectral amplitude coding optical code division multiple access (SAC-OCDMA) system. ...
