| Zusammenfassung: | The present invention relates to a receiver for iteratively decoding by using a logarithm likelihood ratio (LLR) approximation scheme, and relates to a signal process method thereof. According to the present invention, a new approximation method is provided in order to calculate an essential equation, which includes calculations of exponent and logarithm, to correct errors caused by defects of a channel, and so it is possible to maintain low complexity and to reduce deterioration of performance. |
