摘要： Systems and methods for joint training of beam patterns in a system having a transmitter and a receiver. Initial transmit and receive beam pattern vectors are first selected. The beam pattern vectors are perturbed to produce a plurality of perturbed transmit and receive beam pattern vectors. A received signal power between the transmitter and the receiver is estimated for each combination of the perturbed transmit and the perturbed receive beam pattern vectors. The transmit and receive beam pattern vectors having a highest received signal power are applied to the transmitter and the receiver respectively. The perturbation, estimation, and application steps are iterated until the received signal power meets a convergence criterion.

摘要： Steroids containing a cyclohexene moiety are efficiently oxidized to the corresponding α,β-unsaturated ketone using copper iodide and t-butyl hydroperoxide. A steroid compound containing the α,β-unsaturated ketone structure is efficiently converted to the corresponding vicinal diol using a hydroborating reagent followed by oxidative workup, e.g., borane followed by sodium perborate. Benzoyl and substituted benzoyls are superior protecting groups for hydroxyl groups present in the compounds.
