In this paper an FPGA-based System-on-Chip (SoC) implementation of a flexible digital radio is presented and evaluated. The implemented transmitter is able to perform a direct up-conversion of a baseband signal to RF operating in the gigahertz frequency range as well as it enables the simultaneous transmission of two different carriers, each one having a different modulation, bandwidth, etc. The developed...
In this letter, we present a new all-digital multichannel multimode transmitter architecture. The main novelty is the development of an agile radio transmitter where the digital up-conversion to RF operating in the gigahertz frequency range and the multichannel transmission capacity are embedded into a single field-programmable gate array device. Its high flexibility and fast switching of the carriers'...
