Abstract: A User Equipment and method for transmitting a random-access radio frequency (RF) signal by applying Asynchronous Coded Multiple Access (ACMA) in a communication system employing Orthogonal Frequency Division Multiplexing (OFDM) is described. The method including: encoding an information stream as OFDM symbols using a low rate Forward Error Correction (FEC) coding suitable for Successive Interference Cancellation (SIC) to form a payload; generating a burst, including symbols, by performing an inverse fast Fourier transform on a unique word (UW) multiplexed with the payload; and synchronizing a transmission of each of the symbols of the burst with consecutive symbol-start instants. The UW includes a plurality of Zadoff-Chu (ZC) like sequences disposed in a subset of consecutive symbol-start instants of the burst. A receiver detects burst arrival by searching for consecutive ZC-like sequences. Channel state estimation can be performed by using the UW with additional ZC-like sequences in the burst.

Abstract: An azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic is formed via an oxocycloalkenyl isoxazolium anhydrobase and its dimer. The dimer can be used to form mono- and dihydrazones, which can be an azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic. A method of preparation of the dimer and the azasteroid mimic or an intermediate for the preparation of an azasteroid and azasteroid mimic occurs with hydrazonation and, optionally, a subsequent dehydrazonation. The dimer can be converted by inserting a nitrogen atom into the six membered ring of to a C-17 position cyclohexenone moiety of the dimer to yield a reduced tetrazolo[1,5-a]azepin-8-yl group. A subsequent hydrozone formation at a benzylic ketone can be carried out to generate an azasteroid mimic with a (triazol-4-yl)imino substituent. Monohydrazones can be converted to their thione equivalents.
