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...
متن کاملEqualization of linearly frequency-selective fading channels
A simple technique for removing intersymbol interference (ISI) introduced by “linearly frequency-selective” fading channels is presented. The technique involves the optimization of the overall impulse response of the transmit and receive filters and effectively reduces the channel to one which is flat fading. Computer simulation results show that this equalization method works for channels with...
متن کاملFixed-lag blind equalization and sequence estimation in digital communications systems using sequential importance sampling
We present methods for fixed-lag smoothing using Sequential Importance sampling (SIS) on a discrete non-linear, non-Gaussian state space system with unknown parameters. Our particular application is in the field of digital communication systems. Each input data point is taken from a finite set of symbols. We represent the transmission media as a fixed filter with a finite impulse response (FIR)...
متن کاملTransmitter redundancy for blind estimation and equalization of time- and frequency-selective channels
Joint mitigation of timeand frequency-selective fading is an important and challenging problem in mobile communications. Relying on transmitter-induced redundancy, we propose novel channel estimation and symbol recovery approaches for blind identification and equalization of timeand frequency-selective channels, where the time variation is modeled deterministically by a basis expansion. The res...
متن کاملBlind equalization of multiuser CDMA channels: a frequency-domain approach
The blind estimation of mixing channels resulting from frequency selective fading and multipath in a multiuser CDMA system is an important problem in wireless communications. We present a novel frequency-domain approach using second order spectral statistics for recovering the unknown channels. Unlike other methods which are based on time-domain analysis we make no particular assumption about t...
