  • Publication number: 20160028268
    Abstract: A wireless charging system is provided that includes a charger portion that receives one or more portable elements for charging wirelessly. The charger portion controls the amount of power needed to charge the one or more portable elements. An inband communication module receives inband communications with the one or more portable elements using a random access mode. The charger portion utilizes the inband communications to determine how much power is needed, via energy based reporting, to charge the one or more portable elements that avoids conveying identification information.

  • Publication number: 20130142128
    Abstract: A wireless communication system is provided that includes a base station receiving a plurality of input signals that are selectively provided to a plurality of precoders. The precoders perform precoding operations on the input signals and output a first signal. The base station includes an algorithm that minimizes total transmit power per antenna under signal to interference and noise ratio (SINR) target constraints or maximizes the SINR under a sum of power constraint so as to determine power allocation and obtain efficient precoders. A number of mobile receiver units receive the first signal and performs their respective operations to extrapolate the linear estimate of the input signals.

  • Patent number: 8094641
    Abstract: A wireless device has a BRP-CRP interface that includes a dual-port frame memory having a first access port and a second access port in which data can be written to the dual-port frame memory through the first access port at the same time that data is read from the dual-port frame memory through the second access port. A bit rate processor performs bit rate processing on input data and writes data resulting from the bit rate processing to the dual-port frame memory through the first access port. A chip rate processor reads data from the dual-port frame memory through the second access port and performs chip rate processing on the data read from the dual-port frame memory. A data processor executes a software application that writes data to the dual-port frame memory through the first access port and reads data from the dual-port frame memory through the second access port.
