Iterative channel estimation for higher order modulated STBC-OFDM systems with reduced complexity
(Korean Society for Internet Information, 2016-06-30)
In this paper, a frequency domain Expectation-Maximization (EM)-based channel estimation algorithm for Space Time Block Coded-Orthogonal Frequency Division Multiplexing (STBC-OFDM) systems is investigated to support higher ...
Radio resource management for user-relay assisted OFDMA-based wireless networks
Orthogonal frequency division multiple access (OFDMA) based relay assisted networks are important for current and next-generation wireless networks since they have great potential to provide high data rate to users at ...
Low complexity ZF receiver for orthogonal SFBC-OFDM in broadband wireless channels
(Institution of Engineering and Technology, 2006-04)
Orthogonal space-frequency block coded (SFBC) orthogonal frequency division multiplexing (OFDM) systems are analysed in broadband wireless channels where adjacent subcarriers do not have the same channel coefficients and ...
Performance evaluation of multicast MISO-OFDM systems
In this paper, we analyze the performance of multicast orthogonal frequency division multiplexing (OFDM) systems with single and multiple transmit antennas. We show that the resource allocation that includes the subcarrier ...
