An Alternative Approach to Minimum Mean-Squared Error DFE with Finite Length Constraints
نویسنده
چکیده
An alternative approach to decision-feedback equalization with finite impulse response feedforward and feedback filters is presented. Instead of the conventional design criterion of minimum mean-squared error (MMSE), a maximum signalto-noise ratio criterion is employed. After derivation of the optimum filters, the MMSE solution is reviewed. It is shown via matrix manipulations, that both solutions are identical, if a bias in the MMSE solution is removed.

Mmse Dfe for High–rate Mimo Transmission over Channels with Isi
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.
متن کاملOn the robustness of the finite-length MMSE-DFE with respect to channel and second-order statistics estimation errors
The finite-length minimum mean square error decision-feedback equalizer (MMSE-DFE) is an efficient structure mitigating intersymbol interference (ISI) introduced by practically all communication channels at high-enough symbol rates. The filters constituting the MMSE-DFE, as well as related performance measures, can be computed by assuming perfect knowledge of the channel impulse response and th...
متن کاملMinimum mean-squared error decision-feedback equalization for digital subscriber line transmission with possibly correlated line codes
Most of the published theory on the optimal performance of decision-feedback equalization under the MMSE criterion addresses the transmission of i.i.d. symbol sequences only. This paper presents a theory which accommodates the case of correlated symbol sequences. It also considers the use of a fractionally spaced forward filter in the decision-feedback equalizer (DFE). Two limiting conditions a...

MC-CDMA (MultiCarrier Code Division Multiple Access), currently regarded as a promising multiple access scheme for broadband communications, is known to combine the advantages of an OFDM-based (Orthogonal Frequency Division Multiplexing), CP-assisted (Cyclic Prefix) block transmission with those of CDMA systems. Recently, it was recognized that DS-CDMA (Direct Sequence) implementations can also...
متن کاملMinimum Symbol-Error-Rate Equalisation
The equalisation topic is well researched and a variety of solutions are available. The MAP sequence detector provides the lowest symbol error rate (SER) attainable, and the MLSE offers a near optimal solution. However, these optimal techniques are not yet practical for high-level modulation schemes, due to their computational complexity. Linear equaliser or linear-combiner DFE are practical sc...
