Minimum-SER linear-combiner decision feedback equaliser
نویسنده
چکیده
The paper considers the conventional decision feedback equaliser (DFE) that employs a linear combination of the channel observations and past decisions. An expression of the symbol error rate (SER) is derived for the linear-combiner DFE with the general M-PAM constellation by utilising a geometric translation property of decision feedback. A method is developed to optimise the coefficients of the linear-combiner DFE to achieve the minimum-SER (MSER) solution. The performance of this MSER linear-combiner DFE is superior to the usual minimum mean square error (MMSE) solution.

Minimum 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...
متن کاملSpace-time decision feedback equalisation using a minimum bit error rate design for single-input multiple-output channels
This contribution proposes a minimum bit error rate (MBER) decision feedback equaliser (DFE) designed for single-input multiple-output (SIMO) systems employing a quadrature phase shift keying (QPSK) modulation scheme. It is shown that this MBER design is superior over the standard minimum mean square error DFE in the SIMO scenario considered, in terms of the achievable system bit error rate. A ...
متن کاملMultiple hyperplane detector for implementing the asymptotic Bayesian decision feedback equalizer
Abstract— A detector based on multiple-hyperplane partitioning of the signal space is derived for realizing the optimal Bayesian decision feedback equaliser (DFE). It is known that the optimal Bayesian decision boundary separating any two neighbouring signal classes is asymptotically piecewise linear and consists of several hyperplanes, when the signal to noise ratio (SNR) tends to infinity. Th...

متن کاملDevelopment of fuzzy system based channel equalisers
Channel equalisers are used in digital communication receivers to mitigate the effects of inter symbol interference (ISI) and inter user interference in the form of co-channel interference (CCI) and adjacent channel interference (ACI) in the presence of additive white Gaussian noise (AWGN). An equaliser uses a large part of the computations involved in the receiver. Linear equalisers based on a...
