Enhanced architecture to increase the dynamic range of SDR receivers
This paper proposes an architecture to increase the dynamic range of the analog to digital signal conversion. Preferably, such an architecture will witness more applicability in the wideband digital receivers for software-defined radio. It is based in passive circuitry followed by two analog-to-digital converters that acquire the incoming analog signal, and then digital signal processing is applied to reconstruct the signal. We will demonstrate clear improvements related to the case when only one analog-to-digital converter is used. Also, this architecture will be validated through several simulations, in which it will be subjected to common modulated signals that confirms the validity of such an architecture.
