Title: Ripple detection and cancellation for voltage regulator circuits
Inventor: YAZDI SIAVASH
IPC: H02M1/14
Filed: 2019-01-08
Abstract: Techniques are described for ripple detection and cancellation in switching voltage regulator circuits. For example, in a switching voltage converter, a voltage is up-converted or down-converted by switching high side and low side switches and passed through a low-pass filter for averaging. While the act of switching can result in conversion of the voltage with good efficiency, it also typically generates ripples on the output voltage, which can be undesirable in some applications. Embodiments use the switching voltage, the output voltage, and a feed-forward loop to generate a current cancellation signal to have particular gain, timing, and polarity that effectively emulates the complement of the inductor ripple current. The cancellation current signal can be injected into the output node, such that the cancellation current signal sums with the inductor ripple current at the output node, thereby at least partially cancelling the effect of the inductor ripple current.

Title: Parallel transmission of preamble sequences with data layers for improved data detection
Inventor: CAO YIQING
IPC: H04W72/04
Filed: 2019-03-25
Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-orthogonal multiple access (NOMA) systems), a base station may serve a large number of user equipments (UEs) on the uplink. To improve detectability for these uplink transmissions (e.g., if reference signals are not available for the transmissions), the UEs may implement parallel transmissions of preambles with uplink data. A UE may split th uplink data into one or more data layers, and may select one or more preamble layers to transmit superposed with the data layers. These preambles may be sequences known to both the UE and the base station to aid in detectability. The UE may assign different signature sequences to each of these layers based on cross-correlation values (e.g., assigning sequences with higher cross-correlation values to the data layers for improved detectability), and may scramble the layers into a single shared signal for transmission.
