In multi-antenna transceivers with all-digital beamforming, the number of radio frequency (RF) chains necessarily equals the number of antennas, which entails a large hardware complexity and power consumption when deploying large antenna arrays. …
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 …
In this paper, the problem of joint sub-channel assignment, antenna selection, and power control in the downlink (DL) of an orthogonal frequency division multiple access (OFDMA) femtocell network is investigated in order to maximize system …
Off-body data communication for firefighters and other rescue workers is an important area of development. The communication with a moving person in an indoor environment can be very unreliable due to channel fading. In addition, when considering …
Off-body wireless data communication using textile antennas integrated into clothing increases the safety of rescue workers operating in an indoor environment as vital information can be communicated to the command station. The indoor radio …
The quality of experience (QoE) of IP-packetized streaming video is affected by both packet loss and packet delay variations. When the network delivering the video content contains a wireless link, occasional deep fades give rise to bursts of packet …
This contribution deals with the carrier frequency offset estimation for a flat-fading Multiple-Input Multiple-output (MIMO) channel using a training sequence. The resulting Maximum Likelihood (ML) estimation entails solving a maximization problem …
