A degrees of freedom-optimal scheme for SISO X channel with synergistic alternating CSIT
Wagdy, Ahmed; El-Keyi, Amr; Khattab, Tamer; Nafie, Mohammed ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)In this paper, the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel are investigated. Three cases are considered for the availability of channel state information at the transmitters ... -
Modified QR-D and MMSE PMI selection technique for MIMO closed loop spatial multiplexing in LTE/LTE-advanced
Wagdy, Ahmed; Khattab, Tamer; Sourour, Essam A. (2013 , Conference Paper)Limited feedback closed-loop spatial multiplexing evolved as an attractive technique during the development of Multi Input Multi Output (MIMO) in Long Term Evolution (LTE). Spatial multiplexing involves transmitting ... -
On the synergistic benefits of alternating CSIT for X channel within a four-symbol channel extension
Wagdy, Ahmed; El-Keyi, Amr; Khattab, Tamer; Nafie, Mohammed ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we investigate the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). Three cases are considered for ...
