Space-Time-Frequency Degrees of Freedom: Fundamental Limits for Spatial Information
Leif Hanlen Thushara Abhayapala
We bound the number of electromagnetic signals which may be observed over a frequency range a time interval within a sphere of radius . We show that the such…
Bounds on Space-Time-Frequency Dimensionality
Leif Hanlen, Thushara Abhayapala
We bound the number of electromagnetic signals which may be observed over a frequency range for a time within a region of space enclosed by a radius . Our result implie…
Spatial Precoder Design for Space-Time Coded MIMO Systems: Based on Fixed Parameters of MIMO Channels
Tharaka A. Lamahewa, Rodney A. Kennedy, Thushara D. Abhayapala +1
In this paper, we introduce the novel use of linear spatial precoding based on fixed and known parameters of multiple-input multiple-output (MIMO) channels to improve the performan…
MIMO Channel Correlation in General Scattering Environments
Tharaka A. Lamahewa, Rodney A. Kennedy, Thushara D. Abhayapala +1
This paper presents an analytical model for the fading channel correlation in general scattering environments. In contrast to the existing correlation models, our new approach trea…
Non-coherent Rayleigh fading MIMO channels: Capacity Supremum
Rasika R Perera, Tony S Pollock, Thushara D Abhayapala
This paper investigates the limits of information transfer over a fast Rayleigh fading MIMO channel, where neither the transmitter nor the receiver has the knowledge of the channel…
Performance of Gaussian Signalling in Non Coherent Rayleigh Fading Channels
Rasika Perera, Tony Pollock, Thushara Abhayapala
The mutual information of a discrete time memoryless Rayleigh fading channel is considered, where neither the transmitter nor the receiver has the knowledge of the channel state in…
