Joint Channel Estimation and Equalization in Massive MIMO Using a Single Pilot Subcarrier
Danilo Lelin Li, Arman Farhang
The focus of this letter is on the reduction of the large pilot overhead in orthogonal frequency division multiplexing (OFDM) based massive multiple-input multiple-output (MIMO) sy…
Low-Complexity Equalization and Detection for OTFS-NOMA
Stephen McWade, Mark F. Flanagan, Arman Farhang
Orthogonal time frequency space (OTFS) modulation has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this…
Downlink Precoding for FBMC-based Massive MIMO with Imperfect Channel Reciprocity
Hamed Hosseiny, Arman Farhang, Behrouz Farhang-Boroujeny
In this paper, a practical precoding method for the downlink of filter bank multicarrier-based (FBMC-based) massive multiple-input multiple-output (MIMO) is developed. The proposed…
Joint CFO and Channel Estimation for RIS-aided Multi-user Massive MIMO Systems
Sumin Jeong, Arman Farhang, Nemanja Stefan Perović +1
Accurate channel estimation is essential to achieve the performance gains promised by the use of reconfigurable intelligent surfaces (RISs) in wireless communications. In the uplin…
