Mmse Dfe for High–rate Mimo Transmission over Channels with Isi
نویسنده
چکیده
Minimum mean-squared error decision-feedback equalisation (DFE) for joint spatial/temporal equalisation is derived. Here, no finite length assumptions are made but asymptotic results, i.e., ultimate limits are studied. The performance of MMSE DFE for transmission over MIMO ISI channels is assessed by means of numerical simulations for typical high-rate wireless scenarios.

MMSE Beamforming for SC-FDMA Transmission over MIMO ISI Channels
We consider transmit beamforming for single-carrier frequency-division multiple access (SC-FDMA) transmission over frequency-selective multiple-input multiple-output (MIMO) channels. The beamforming filters are optimized for minimization of the sum of the mean-squared errors (MSEs) of the transmitted data streams after MIMO minimum mean-squared error linear equalization (MMSE-LE), and for minim...
متن کاملMulti-input multi-output fading channel tracking and equalization using Kalman estimation
This paper addresses the problem of channel tracking and equalization for multi-input multi-output (MIMO) time-variant frequencyselective channels. These channels model the corrupting effects of intersymbol interference (ISI), co-channel interference (CCI), and noise. A firstorder autoregressive model describes the MIMO channel variation, and tracking is performed by a Kalman filter. Hard decis...

With the rapid growth of digital communication in recent years, the need for high speed data transmission is increased. OFDM is a promising solution for achieving high data rates in mobile environment, due to its resistance to ISI, which is a common problem found in high speed data communication. A multiple-input multiple-output (MIMO) communication System combined with the orthogonal frequency...
متن کاملMMSE DFE for MIMO DFT-spread OFDMA
In this work, we propose a Decision feedback equalizer (DFE) for Multiple Input Multiple Output (MIMO) DFT-spread OFDMA. This DFE can handle Multiple users, multiple antennas at the transmitter and receiver and the intersymbol interference in the received symbols of the DFT-spread OFDMA. The conventional method used in DFT-spread OFDMA is linear Frequency domain equalization (FDE). The DFE, wit...
متن کاملJoint Transmit/Receive MMSE Filtering for Single-carrier MIMO Spatial Multiplexing
Multiple-input multiple-output (MIMO) spatial multiplexing is a powerful technique to increase the transmission data rate. However, if MIMO spatial multiplexing is applied to single-carrier (SC) block transmissions, it suffers from the intersymbol interference (ISI) as well as the inter-antenna interference (IAI). In this paper, we propose a joint transmit/receive frequency-domain (FD) filterin...
