Question

Which among the following terms define the design space used to describe the development of software defined radio?

(a) Digital access bandwidth and programmability

(b) Digital access bandwidth and feasibility

(c) Programmability and feasibility

(d) Analog access bandwidth and feasibility

The question was asked by my school principal while I was bunking the class.

My question is from Building CRA on SDR Architecture in section Cognitive Radio Architecture of Cognitive Radio

Answer 1

The correct answer is:

(a) Digital access bandwidth and programmability

In the context of Software Defined Radio (SDR) and Cognitive Radio Architecture (CRA), the design space typically refers to the key parameters that define the system's capabilities and flexibility. These parameters include:

• Digital access bandwidth: This refers to the bandwidth available for digital signal processing, which is crucial for supporting various communication standards and protocols in an SDR.

• Programmability: One of the core features of SDR is the ability to reprogram the radio to support different communication protocols or frequencies, making programmability an essential factor in the design space.

These two parameters are central to the development of Software Defined Radios, as they determine the system's adaptability, performance, and capacity to handle multiple communication standards or waveforms.

Therefore, the correct choice is (a) Digital access bandwidth and programmability.
