Burst synchronization on unknown frequency selective channels withco-channel interference using an antenna arrayIn this work, burst oriented data transmission ... D Astely,A Jakobsson,AL Swindlehurst - Railroad Conference 被引量: 0发表: 1995年 Adaptive antenna array for OFDM systems with cochannel ...
In this paper, we study the blind equalization problem of time-varying (TV) systems where the channel variations are too rapid to be tracked with conventional adaptive equalizers. We show that using a finite Fourier basis expansion, a TV antenna array system can be cast into a time-invariant...
antenna with two isolated channels, workingAntenna has row(s) of antenna elements (7) forming an array and with parasitic elements (8a, 8b) in the gaps between them and extending parallel to the centre line (C) of the row. Each antenna element transmits and/or receives dual polarised ...
First, make sure you have anantennaor a cable box already installed and set up to go. You may need to attach a coax cable to the antenna or box if it doesn't come with one. When you're ready, connect the other end of the coax cable to theANT INport on the back of your TV, ...
"If you’re a cord cutter, then Channels coupled with an HDHomeRun and antenna is one of the best purchases you can make." — 9to5mac "If live television has been a missing or irritating-to-use piece for your viewing pleasure, Channels plus a networked tuner pulls it neatly into your...
Antenna has row(s) of antenna elements (7) forming an array and with parasitic elements (8a, 8b) in the gaps between them and extending parallel to the centre line (C) of the row. Each antenna element transmits and/or receives dual polarised mutually orthogonal waves defining two mutually...
Turbo processing in transmit antenna diversity systems We consider turbo-trellis-coded transmission over fading multiple-input-multiple-output (M1M0) channels with transmit diversity using space-time block code... G Bauch,J Hagenauer,N Seshadri - 《Annales Des Télécommunications》 被引量: 101发表:...
Consider a multiple antenna broadcast channel composed of one base station (BS) with M transmit antennas and K users each with a single receive antenna. Assuming the channel is at and i.i.d. block fading, the received signal at user i in a given block is (1) where h i ∈ ℂ1×...
DESIGN OF MULTIUSER MIMO FOR LARGE ANTENNA SYSTEMS WITH HYBRID BEAMFORMING A hybrid combination of analog RF beamforming and digital pre-coding is used to improve signal-to-noise ratio and mitigate interference as between an RF base station and a plurality of wireless receivers within a cell area...
A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where there exists a transmitter equipped with multiple antennas, a legitimate receiver and an eavesdropper each equipped with a single antenna. We study the problem of finding the optimal input covariance that maximiz...
