The invention relates to the entertainment industry. The oxo-cations are selected from MnO3+, VO3+, VO2+, WO22+, MoO22+, TiO2+, ZrO2+ and mixtures thereof, and the halogen complex anions have the structure MXab\u2212, wherein M is selected from B, Ti, Zr, Si, Al, X is selected from F, Cl, Br, I, a is an integer of between 3 and 6 and b is an integer of between 1 and 4. Preferably, the bottom of the prismatic outer can is covered with only one piece of the insulating sheet, and all edges of the insulating sheet is positioned above the bottom of the outer can. Each correlator then decovers the despread samples to provide decovered \u201chalf-symbols\u201d and further demodulates the decovered half-symbols with pilot estimates to generate correlated symbols. The system includes a helical compressor unit, a motor unit dedicated to the helical compressor unit for driving the helical compressor unit, and a control unit for adjusting a rotational speed of the motor unit and to generate a predefined discharge rate of compressed air from the helical compressor unit, independently of a drive assembly of the vehicle. Also disclosed is a method of preparing the iridium phosphorescent dendrimer and an electroluminescent device including the iridium phosphorescent dendrimer.
