Adaptive pilot allocation for estimating sparse uplink MU-MIMO-OFDM channels

We consider uplink multiuser multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication. The transmit (Tx) side of the envisaged system consists of several single-antenna users or/and several …

Parameter estimation and channel reconstruction based on compressive sensing for ultra-wideband MB-OFDM systems

Dynamic link performance analysis of a rescue worker's off-body communication system using integrated textile antennas

The performance of wireless data communication for fully equipped firemen walking indoors and communicating through textile patch antennas integrated into their clothing is evaluated. The small-scale fading experienced in the building is …

Iterative residual frequency offset correction for OFDM systems

The estimation and tracking of the fractional carrier frequency offset (CFO) is a crucial issue in the implementation of orthogonal frequency division multiplexing (OFDM) systems. In this contribution, we present a novel code-aided fractional CFO …
