Adaptive Phase Rolling for Opportunistic Beamforming in OFDMA Systems with a Small Number of Users
The performance of opportunistic beamforming might be degraded if the number of users is small. This paper proposes an adaptive opportunistic beamforming technique for orthogonal frequency division multiple access systems, which can produce good results even with a small number of users. This paper...
