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 rateThis 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» 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.
