Abstract
This paper investigates the upper and lower bounds on achievable secrecy rate of multiple-input multiple-output (MIMO) wiretap channels by employing zero-forcing (ZF) detectors at, both the legitimate and malicious receivers' sides. Particularly, both large (i.e., gamma distribution) and small scale (i.e., Rayleigh distribution) fadings are taken into considerationwith the purpose of better simulating some practical scenarios. Motivated by previous works, bounds of achievable secrecy rate for MIMO wiretap channels over uncorrelated and min semi-correlated Rayleigh fading are derived with closed-form expressions. Furthermore, an asymptotic scenario in which the number of antennas tends to infinity is evaluated. Finally, thecloseness of our analytical expressions is corroborated through simulation results.
