Question

Which of the following is not a layer in the soft radio model proposed by Srikanteswara?

(a) Application layer

(b) Configuration layer

(c) Processing layer

(d) Tunneling layer

The question was posed to me in examination.

My query is from Digital Architecture Tradeoffs in section Technology Tradeoffs in Software Defined Radio of Cognitive Radio

Answer 1

The correct answer is:

(d) Tunneling layer

The soft radio model proposed by Srikanteswara generally includes layers such as the Application layer, Configuration layer, and Processing layer, but Tunneling layer is not typically part of this model. Tunneling layers are more commonly discussed in network protocols and VPN technologies, not in the context of soft or software-defined radio architectures.
