—In this paper, the receivers with adaptive equalizer and turbo decoder are investigated for orthogonal frequency division multiplexing-code division multiple access (OFDM-CDMA) systems in multipath channels. The de-spreading equalizer which combines de-spreading and equalization is used to mitigate the MAI and ISI. The stochastic gradient based LMS(More)
A new pyrene-based chemosensor (1) exhibits excellent selectivity for Fe3+ ions over a wide range of tested metal ions Ag+, Ca2+, Cd2+, Co2+, Cu2+, Fe2+, Hg2+, K+, Mg2+, Mn2+, Ni2+, Pb2+, and Zn2+. The binding of Fe3+ to chemosensor 1 produces an emission band at 507 nm due to the formation of a Py-Py* excimer that is induced by Fe3+-binding. The binding(More)
