Iterative EM-based channel estimation for STBC-OFDM
In this paper, an iterative EM based channel estimation algorithm is studied for STBC-OFDM systems. Compared to the time domain EM based channel estimation algorithm which needs matrix inversion, a frequency domain EM based ...
Radio resource management for OFDMA-based mobile relay enhanced heterogenous cellular networks
In this paper, we focus on the radio resource management problem for the Orthogonal Frequency Division Multiple Access (OFDMA)-based mobile relay-enhanced het erogenous cellular networks. We combine mobile relaying and ...
Queue-aware resource allocation for OFDMA-based mobile relay enhanced networks
Mobile relay assisted OFDMA networks that are considered as a good candidate in future deployment scenarios for coverage extension and lower deployment costs are promising solutions for provision of ubiquitous high-data-rate ...
Fairness aware resource allocation for downlink MISO-OFDMA systems
In this paper, a resource allocation problem for downlink multiple input-single output orthogonal frequency division multiple access (MISO-OFDMA) systems is investigated. The problem is defined as maximizing the minimum ...
Resource allocation for user-relay assisted MISO-OFDMA networks
The next generation cellular networks request higher capacity and coverage that user-relay assisted Orthogonal Frequency Division Multiple Access (OFDMA) networks are costeffective solutions to meet these demands. These ...
