1. A method for signal processing across wireless standards comprising:
sampling, at a sample processing unit (SPU), multiple outputs at a baseband spectrum from a signal processing engine (SPE);
translating, using multiple digital up converters (DUCs) within the sample processing unit (SPU), the multiple outputs from the SPE to multiple intermediate frequency (IF) signals corresponding multiple wireless standards or multiple carriers;
aggregating, at a carrier aggregation (CA) combiner, the multiple IF signals into an aggregated signal; and
outputting the aggregated signal to a digital-to-analog converter (DAC) for digital-to-analog conversion.
