Abstract It is accepted that the infrared radiometry has potential in observing and organizing animal life behaviour. While doing such kind of studies a few issues normally rise. We have studied such issues in this work. Also, we took sample data for measuring the solid angles with many animal kinds.... Read More


Multiuser Multiple-input Multiple-output Orthogonal Frequency Division Multiplexing (MU-MIMO-OFDM) SystemMultiuser Multiple-input Multiple-output Orthogonal Frequency Division Multiplexing (MU-MIMO-OFDM) System

Abstract We have developed algorithms for multiuser multiple-input multiple-output orthogonal frequency division multiplexing (MU-MIMO-OFDM) system. For applying inter and intra-user interferences, we have used correct channel state information based on zero force beam forms. Besides, we have presented experimental results that prove the user selection algorithm to compare the generalized multicarrier semi orthogonal user selection.... Read More


Synthesized Low Pass Wave Digital Filter Models for Measuring Element Values

Biljana Stosic and Nebojsa S Doncov

https://doi.org/10.6025/jdp/2022/12/2/42-49

Abstract We have presented the synthesized low pass wave digital filter models. First, we have measures the element values of the reference lowpass structure for a few specifications. The resulting equations have produced the network elements of the reference structure to ease the procedures for designs. Then, the design is solved by direct transformation of reference structure, i.e., its one-port elements... Read More
