Abstract:
1. A receiving apparatus in a wireless communication system, the apparatus comprising: an estimator for estimating channels of a desired signal and at least one interference signal through a Joint Channel Estimation (JCE), for estimating noise using the channel estimation values of the desired signal and the at least one interference signal, for calculating a mean interference power of each interference signal using the channel estimation value of the at least one interference signal, and for calculating a mean noise power using the noise estimation value; a channel compensator for channel-compensating burst data using the channel estimation value of the desired signal received from the estimator; and a demodulator for calculating a noise variance value by adding the mean noise power to the at least one mean interference power, and for creating Log Likelihood Ratio (LLR) data by demodulating the channel-compensated data using the noise variance value.
