    摘要: An embodiment of the invention is a predistortion approach to linearize a power amplifier without frequency conversion of the RF signals by using envelope and phase detectors to detect the error to be corrected, and then one or more analog multiplier(s) and a DSP-based processor. For the analog embodiment, the inherent nature of the analog circuitries allows digital predistortion processing structured directly at the RF band, and enables a single power amplifier to support multi-modulation schemes, multi-carriers and multi-channels. As a result, the predistortion architecture is particularly suitable for wireless transmission systems, such as base-stations, repeaters, and indoor signal coverage systems. The wireless system performance can be improved and upgraded just by using the new PA module rather than change or rebuild new subsystem in existing base station. The analog embodiment can also mix and match its analog multipliers with other analog components such as phase splitters, phase shifters, attenuators, filters, couplers, mixers, low-noise amplifiers, buffers, envelope detectors, and etc., to provide additional features.

    摘要: Enabling innovative merchant transaction pricing capability, while improving pricing process efficiency, is disclosed. When a merchant submits financial transaction account records to a payment processor for payment, the payment processor utilizes granular transaction data to calculate complex merchant transaction pricing rules. The system accesses individual transaction data, aggregate transaction data, transaction history, customer data, merchant data and product data to enable flexible, innovative and dynamic pricing capabilities that increase revenue and increase customer satisfaction.
