Equalization Strategie for Transmission over Space and Time
نویسندگان
چکیده
An overview on equalization schemes applicable for point-to-point communication over MIMO ISI channels is given, i.e., channels which suffer form both, multiuser interference between the data streams transmitted in parallel and intersymbol interference due to the dispersive (frequencyselective) nature of the channel. Spatial, temporal and combined spatial/temporal equalization strategies for dealing with these types of interferences are discussed. In particular, linear and decision-feedback equalization, and equalization based on singular value/eigenvector decomposition and lattice basis reduction, respectively, are treated. The underlying mathematical principle, utilized in these schemes, is stated in each case. Via numerical simulations, the performance of selected equalization strategies is compared.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

This paper addresses the issue of advanced equalization methods for space-time communications over MIMO broadband wireless channel. Instead of resorting to conventional multiuser detection techniques (based on the straightforward analogy between antennas and users), we adopt a different point of view and separate time equalization from space equalization, thus introducing a higher degree of fre...

In a frequency-selective fading channel, the transmission performance of single-carrier (SC) transmission significantly degrades due to severe inter-symbol-interference (ISI). In this paper, the joint use of space-time transmit diversity (STTD), receive antenna diversity and frequency-domain minimum mean square error (MMSE) equalization in SC transmission is studied. Space-time encoding and dec...

We consider turbo equalization of space–time-coded transmission over frequency-selective fading multiple-input–multiple-output (MIMO) channels. A MIMO finite-impulse-response prefilter is proposed and shown to reduce the turbo equalizer complexity significantly at a small performance loss. Advantages of the proposed scheme are that we do not alter the equalization algorithm or require the chann...
