We present capacity analysis for multiple-input multiple-output (MIMO) system under a low signal-to-noise ratio (SNR) regime. We have selected a composite fading channel that considers Weibull fading for multipath and gamma fading for shadowing. We h

Summary In this paper, multiple-input multiple-output (MIMO) system performance is evaluated over composite Weibull–Gamma (WG) fading channel using antenna selection (AS) techniques. WG fading channel is considered to model multipath and shadowing

Frequency division duplex (FDD) and time-division duplex (TDD) are two different ways of executing the downlink and uplink transmission over a given frequency band. In which, TDD is the superior mode due to less pilots’ requirement than FDD and its

The orthogonal space–time block codes (OSTBCs) increase the diversity order of a multiple-input multiple-output (MIMO) system at a reasonable cost of complexity. However, the precoding technique in which complete channel knowledge is available at t
