Performance Analysis of Short Packet Communications With Multiple Eavesdroppers

This paper studies the performance of short packet communications in presence multiple eavesdroppers. We start our investigation by examining fading wiretap channel, where communication is overheard non-colluding single antenna A closed-form expression for average secrecy throughput derived, when transmitter has a antenna. The Monte-Carlo simulations show close match analytical with numerical results. Moreover, optimal blocklength value that maximizes determined, observed and then extend analysis case multiple-antenna consider artificial noise (AN) to confuse obtained scenario two-antenna two eavesdroppers results demonstrate validity approximation compared simulations. further reveal an increased number antennas at associated higher applying AN helps eliminate harm
