Performance of spatial modulation in the presence of channel estimation errors
(IEEE-INST Electrical Electronics Engineers Inc, 2012)
This work investigates the negative effects of channel estimation errors on the performance of spatial modulation (SM) when operating over flat Rayleigh fading channels. The pairwise error probability of the SM scheme is ...
Broadband impedance matching via lossless unsymmetrical lattice networks
(Elsevier GMBH Urban & Fischer Verlag, 2012)
In this paper a broadband impedance matching network (equalizer) design algorithm has been proposed. In the equalizer a lossless unsymmetrical lattice network has been utilized. The branch impedances of the lattice network ...
Nondata-aided joint channel estimation and equalization for OFDM systems in very rapidly varying mobile channels
(IEEE-INST Electrical Electronics Engineers Inc, 2012)
This paper is concerned with the challenging and timely problem of joint channel estimation and equalization for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very ...
Super-orthogonal trellis-coded spatial modulation
(Inst Engineering Technology-IET, 2012)
Spatial modulation (SM) which employs the indices of multiple transmit antennas to transmit information in addition to the conventional M-ary signal constellations is a novel transmission technique that has been proposed ...
Broadband double-matching via lossless unsymmetrical lattice networks
(Istanbul University, 2012)
In this paper a broadband double-matching network design algorithm has been presented. In the network an unsymmetrical lattice network has been used. The branch impedances of the lattice network are composed of singly ...
Effect of power and rate adaptation on the spectral efficiency of MQAM/OFDM system under very fast fading channels
(Springer International Publishing Ag, 2012)
In this article the effect of power and rate adaptation on the spectral efficiency of orthogonal frequency division multiplexing (OFDM) systems using M-ary quadrature amplitude modulation (MQAM) is investigated in the ...
