摘要： A charge pump circuit for generating an output voltage is described. Charge pump circuits typically have two branches. As the clocks supplying the branches of a charge pump circuit alternate, the output of each branch will alternately provide an output voltage, which are then combined to form the pump output. The techniques described here allow charge to be transferred between the two branches, so that as the capacitor of one branch discharges, it is used to charge up the capacitor in the other branch. An exemplary embodiment using a voltage doubler-type of circuit, with the charge transfer between the branches accomplished using a switch controller by a boosted version of the clock signal, which is provided by a one-sided voltage doubler.

摘要： The disclosure discloses a multi-antenna signal processing method in an uplink system. The method includes that: after scrambling, modulation, layer mapping, pre-coding, transmission pre-coding, resource mapping and Single Carrier Frequency Division Multiple Access (SC-FDMA) signal generation are performed successively on a coded bit sequence corresponding to each codeword, a resulted signal is transmitted from each transmitting antenna port.
