VERFAHREN UND VORRICHTUNG FÜR KOMBINIERTE SOFT- DECISION-ENTSCHEIDUNGSBASIERTE INTERFERENZUNTERDRÜCKUNG UND DEKODIERUNG |
摘要 |
A method of communications channel coding gain optimization using combined ISI cancellation and turbo decoding is provided. Log-likelihood ratio probabilities with extrinsic values are computed from previous iterations of turbo decoding and used to compute the soft-decision values of channel symbols. The soft-decision values are then used to perform intersymbol interference cancellation and generate refined channel log-likelihood ratio probabilities for the next iteration of turbo decoding. |
