1. A receiving method for use in a telecommunication system in which a number of signal components are detected simultaneously from a received signal received by a receiver, comprising:

  • dividing the received signal in the time domain into blocks of a certain length,subjecting the blocks to simultaneous estimation of user data and channel parameters in the receiver by recursive processing of each block,utilizing placing of dots on an adaptive signal dot matrix in the detection of signal blocks,computing the distance between each respective momentary signal sample of the received signal and vectors pointing to the dots on the signal dot matrix, andassigning each respective momentary signal sample to a respective certain dot on the signal dot matrix by selecting the respective dot where the distance between a respective codebook vector pointing thereto and the respective momentary signal sample is the shortest.
