Optimal Power Assignment for MIMO Channels Under Joint Total and Per-Group Power Constraints

Mahdi Khojastehnia, Ioannis Lambadaris, Ramy H Gohary +1

In this paper we consider a communication system with one transmitter and one receiver. The transmit antennas are partitioned into disjoint groups, and each group must satisfy an a…

Structural Design of Non-Uniform Linear Arrays for Favorable Propagation in Massive MIMO

E. Anarakifirooz, S. Loyka

Favorable propagation (FP) for massive multiple-input multiple-output (MIMO) systems with uniform and non-uniform linear arrays is considered. A gap in the existing FP studies of u…

The Secrecy Capacity of The Gaussian Wiretap Channel with Rate-Limited Help

Sergey Loyka, Neri Merhav

The Gaussian wiretap channel with rate-limited help, available at the legitimate receiver (Rx) or/and transmitter (Tx), is studied under various channel configurations (degraded, r…

On the Capacity of Gaussian MIMO Channels with Memory

Sergey Loyka, Charalambos D. Charalambous

The operational capacity of Gaussian MIMO channels with memory was obtained by Brandenburg and Wyner in [9] under certain mild assumptions on the channel impulse response and its n…

Favorable Propagation for Massive MIMO with Circular and Cylindrical Antenna Arrays

Elham Anarakifirooz, Sergey Loyka

Massive MIMO systems with uniform circular and cylindrical antenna arrays are studied. Favorable propagation property is rigorously shown to hold asymptotically in LOS environment…

Simple Closed-Form Approximations for Achievable Information Rates of Coded Modulation Systems

Maria Urlea, Sergey Loyka

The intuitive sphere-packing argument is used to obtain analytically-tractable closed-form approximations for achievable information rates of coded modulation transmission systems,…
