Timing Advance Estimation and Beamforming of Random Access Response in Crowded TDD Massive MIMO Systems
Sudarshan Mukherjee, Alok Kumar Sinha, Saif Khan Mohammed
Timing advance (TA) estimation at the base station (BS) and reliable decoding of random access response (RAR) at the users are the most important steps in the initial random access…
Information Rate Performance of Massive MU-MIMO Uplink with Constant Envelope Pilot-based Frequency Synchronization
Sudarshan Mukherjee, Saif Khan Mohammed
In this paper, we consider a constant envelope (CE) pilot-based low-complexity technique for frequency synchronization in multi-user massive MIMO systems. Study of the complexity-p…
Constant Envelope Pilot-Based Low-Complexity CFO Estimation in Massive MU-MIMO Systems
Sudarshan Mukherjee, Saif Khan Mohammed
In this paper we consider a constant envelope pilot signal based carrier frequency offset (CFO) estimation in massive multiple-input multiple-output (MIMO) systems. The proposed al…
Low-Complexity CFO Estimation for Multi-User Massive MIMO Systems
Sudarshan Mukherjee, Saif Khan Mohammed
Low-complexity carrier frequency offset (CFO) estimation and compensation in multi-user massive multiple-input multiple-output (MIMO) systems is a challenging problem. The existing…
