Abstract--In a downlink Orthogonal Frequency Division Multiple Access (OFDMA) system, optimally allocating sub-channels across mobile users can require excessive feedback of channe...
In the OFDMA downlink, obtaining Channel State Information (CSI) from users is necessary for the Base Station (BS) to optimize network performance by intelligently allocating resou...
—OFDM is an attractive solution for the design of future wireless communications due to its robustness to dispersion in multipath environments. Additional diversity gains can be ...
