Evolution of Prior Information in SISO Equalization
نویسندگان
چکیده
Soft-input soft-output (SISO) devices play an important role in a variety of algorithms for communications problems. In an iterative structure, soft information is passed between a number of SISO devices, and the ensemble of the soft information evolves with each iteration. We develop and present a framework for analyzing the evolution of this soft information in a class of SISO linear equalizers.

Iterative correction of ISI via equalization and decoding with priors - International Symposium on Information Theory, 2000. Proceedings. IEEE
Abstmct An iterative algorithm is presented for joint equalization and decoding of data that has been transmitted over intersymbol interference (ISI) channels. This differs from well-known “turbo e q u a l h tion” (TEQ) methods, in that the IS1 is removed with a soft-input soft-output (SISO) equalizer via linear or decision feedback equalization (DFE). The data is encoded with a convolutional c...
متن کاملMinimum mean squared error equalization using a priori information
A number of important advances have been made in the area of joint equalization and decoding of data transmitted over intersymbol interference (ISI) channels. Turbo equalization is an iterative approach to this problem, in which a maximum a posteriori probability (MAP) equalizer and a MAP decoder exchange soft information in the form of prior probabilities over the transmitted symbols. A number...

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...

Absfracl-In this paper, we propose a method for analysis of linear turbo equalization that makes use of extrinsic information transfer (EXIT) charts. Given channel knowledge and a timeinvariant set oi linear equalizer coefficients, evolution of soft information in the soft-input soft-output (SISO) equalizer can be estimated via analytically measuring the mutual inionnation between the transmitt...
متن کاملAnalysis of linear turbo equalizer via EXIT chart
In this paper, we propose a method for analysis of linear turbo equalization based on extrinsic information transfer (EXIT) charts. Given channel knowledge and therefore the optimum linear equalizer coefficients, evolution of soft information of the soft-input soft-output (SISO) equalizer can be estimated via computing bit error rates (BER) analytically. Compared to conventional analysis method...
