Analysis of Joint Transmit-Receive Diversity in Downlink MIMO Heterogeneous Cellular Networks
Ralph Tanbourgi, Harpreet S. Dhillon, Friedrich K. Jondral
We study multiple-input multiple-output (MIMO) based downlink heterogeneous cellular network (HetNets) with joint transmit-receive diversity using orthogonal space-time block codes…
Analysis of Heterogeneous Cellular Networks under Frequency Diversity and Interference Correlation
Ralph Tanbourgi, Friedrich K. Jondral
Analyzing heterogeneous cellular networks (HCNs) has become increasingly complex, particularly due to irregular base station locations, massive deployment of small cells, and flexi…
On the Deployment of Cognitive Relay as Underlay Systems
Ankit Kaushik, M. Rehan Raza, Friedrich K. Jondral
The objective of this paper is to extend the idea of Cognitive Relay (CR). CR, as a secondary user, follows an underlay paradigm to endorse secondary usage of the spectrum to the i…
On the Estimation of Channel State Transitions for Cognitive Radio Systems
Ankit Kaushik, Friedrich K. Jondral
Coexistence by means of shared access is a cognitive radio application. The secondary user models the slotted primary users channel access as a Markov process. The model parameters…
Analysis of Non-Coherent Joint-Transmission Cooperation in Heterogeneous Cellular Networks
Ralph Tanbourgi, Sarabjot Singh, Jeffrey G. Andrews +1
Base station (BS) cooperation is set to play a key role in managing interference in dense heterogeneous cellular networks (HCNs). Non-coherent joint transmission (JT) is particular…
