Question

Which among the following is a simple expression of throughput objective?

(a) Rth=kRs where Rs is symbol rate

(b) Rth=kRb where Rb is bit rate

(c) Rth=RsRb where Rs is symbol rate and Rb is bit rate

(d) Rth=Rs/Rb where Rs is symbol rate and Rb is bit rate

This question was addressed to me by my school principal while I was bunking the class.

The origin of the question is Techniques topic in division Cognitive Techniques of Cognitive Radio

Answer 1

The correct option is (a) Rth=kRs where Rs is symbol rate

Explanation: The simple expression of throughput objective is given by Rth=kRs . The complexities involved in the measurement of throughput are due to restricted retransmissions and no coding. As a result, a single bit error leads to packet error. By taking this into account, the expression of throughput is given by Rth=Rb(1-Pe)^l.
