Abstract:
In both wire and wireless communication data are encrypted before transmission to protect active and passive intruder. This project work deals with mathematical model among the relation of:security level, length of encrypted block, SNR at receiving end and throughput. The through put of a network is governed by probability of bit error which is again depends on SNR. Based on above concept impact of modulation scheme on the throughput is also analyzed in this project work. Here, we consider 16-QAM, QPSK and BPSK modulation schemes. We found that performance of 16-QAM is far better than QPSK and BPSK at higher SNR.
