Turbo-equalization: convergence analysis
We investigate a sub-optimal iterative receiver for joint equalization and decoding called Turbo-equalizer. We view the evolution of the error variance of the transmitted symbols through the iterative processing, obtaining convergence analysis. This allows us to predict the asymptotic performance (when the Turbo-equalizer has converged) but also the trigger point observed in its performance.

متن کاملTurbo Equalization and its Applications
In communication systems, the transmitted signals often experience various forms of corruption, and a very destructive one is the inter-symbol interference (ISI), resulting from the signals travelling through multiple paths and arriving with different delays. To compensate for the multipath propagation effect, equalization is often required at the receiver and as a very powerful candidate, the ...
متن کاملTurbo equalization: adaptive equalization and channel decoding jointly optimized
This paper deals with a receiver scheme where adaptive equalization and channel decoding are jointly optimized in an iterative process. This receiver scheme is well suited for transmissions over a frequency-selective channel with large delay spread and for high spectral efficiency modulations. A low-complexity soft-input soft-output -ary channel decoder is proposed. Turbo equalization allows in...
متن کاملAn Efficient Turbo Equalization for Faster than Nyquist Signal
In this paper, we analyzed efficient decoding scheme with faster than Nyquist (FTN) signaling that is transmission method faster than Nyquist theory and increase the throughput. We proposed BCJR equalization model to minimize inter symbol interference when faster than Nyquist signal is transmitted. The presented model utilized interference as branch information and iteratively exchange probabil...
