Subcarrier Allocation Algorithm Based on Greedy-Like in Multi Carrier Code Division Multiple Access Systems
(Kaunas Univ Technology, 2017)
One of the most important issues to be taken into consideration in multi carrier communication systems with multi users is the assignment of the available resources to the users efficiently. Thus, how to determine the ...
A Novel Subcarrier Allocation Algorithm for MC–CDMA Systems
(Slovak Univ Technology, 2016)
Multi carrier modulation techniques such as MC-CDMA are used in high-speed communication applications. Due to MC-CDMA being a multiuser in technology, the subcarrier quantity allocated per user decreases in case the quantity ...
Particle swarm optimization for pilot tones design in MIMO-OFDM systems
(Springer, 2011)
Channel estimation is an essential task in MIMO-OFDM systems for coherent demodulation and data detection. Also designing pilot tones that affect the channel estimation performance is an important issue for these systems. ...
