Abstract
An RF device may include an RF antenna, and an ASIC downstream from the RF antenna. The ASIC may include ADCs configured to generate replica digitized input signals, and DSP cores downstream from the ADCs. Each DSP core may have complex coefficient multipliers and associated delay circuits, and a respective summer downstream from each DSP core. The RF device may also include a processor configured to control the complex coefficient multipliers and associated delay circuits.
