Patent ID: 8027403

Claim:
An equalizing structure for a receiving device of a wireless communication system, in which two or more information signals are transmitted in parallel from one or more transmitters, wherein for the information signals transmit information is modulated onto carrier signals according to a modulation scheme, whereby all possible data symbols are represented as constellation points in a signal constellation of the modulation scheme and whereby the equalizing structure performs, for each information signal, a maximum likelihood detection to determine a constellation point with a minimum Euclidean distance to a received signal vector as a most likely received signal vector by searching over a whole set of possible transmitted signals, the equalizing structure comprising: a channel estimator for detecting channel estimation information in the information signals; and calculating means for calculating a product of channel matrix and transmit signal vector based on the channel estimation information detected by the channel estimator, wherein the calculating means calculates the product of channel matrix and transmit signal vector, wherein a partial product of channel matrix and transmit signal vector based on at least one or a part of the channel estimation information detected by the channel estimator is calculated.
