Interpretation of AF-DF protocols for FitureMulti Layer-IDMA

Abstract

In this article, we investigate the bit error rate (BER) performance in a cooperative relay communication system for multilateral IDMA (ML-IDMA) using the maximum ratio combination (MRC) technique. ). ). We investigate the effect of the number of lines on performance and find the average error rate in bits of the AF relay scheme (Amplify and Forward) using the signal-to-noise ratio (SNR) of the relay connection in closed form. The proposed system for evaluating ML-IDMA performance is provided with a different number of layers and a different number of relays in an ML-IDMA cooperative environment. The simulation results show that the BER performance of a 4-relay IDMA double layer system (K = 2) is approximately 4 dB. In addition, the bandwidth saving is 50%. Ultimately, BER performance deteriorates as the number of layers increases and the proposed system increases bandwidth by approximately 1/K.

Synthesis, Spectral, Antimicrobial and In vitro Antitumorous Studies of Copper based mulltidentate thiosemicarbazones

“…17 This implies substantial electrondelocalisation and a change of bond order occuring during chelation.The coordination through pyridyl nitrogen is confirmed by plane bending vibrations of pyridine ring, dpy(o.p) at 650 cm -1 in free ligand shifting to higher frequencies. [17][18][19] Bands at 1430 cm -1 and 1297 cm -1 with a spacing of ~130 cm -1 corresponding to 1 and 4 nitrato group vibrational modes are seen in the nitrato complex. This confirms terminally N-coordinated monodentate nitrato group coordination in the synthesized complex.…”

“…This confirms terminally N-coordinated monodentate nitrato group coordination in the synthesized complex. 17,19 The spectrum of synthesized "sulpato complex" to complex contains two moderate intensity regions with bands at 923 cm -1 and 463cm -1 due to n 1 and n 2 vibrational modes, correspondingly. The n 3 vibrational mode splits into three weak bands at 1021 cm -1 , 1112 cm -1 , 1226 cm -1 .…”
