Analytical Approximation for Capacity in Massive MIMO Systems
In most existing research on massive multiple-input multiple-output (MIMO) systems, theoretical analysis relies on the assumption that the number of antennas at the base station is infinite. Under this assumpt...

Modeling the Channel Time Variation Inside Moving Vehicle
In this letter, we propose a new stochastic model for the time variation of wireless channel inside the moving vehicle. In the classical Jakes’ model, the receiver is assumed to move at a certain speed relativ...

Parameter Based Channel Estimation for OFDM Systems Over Time-Varying Channels
This paper investigates the parameter-based (PB) channel estimation for orthogonal frequency division multiplexing over time-varying channels. The time-varying channel impulse response (CIR) can be represented...
