Abstract:
PCT No. PCT/FI95/00217 Sec. 371 Date Dec. 18, 1996 Sec. 102(e) Date Dec. 18, 1996 PCT Filed Apr. 13, 1995 PCT Pub. No. WO95/28772 PCT Pub. Date Oct. 26, 1995In a receiving method for multiple access and a receiver for use in a telecommunication system, a number of signal components in a received signal and channel parameters are detected simultaneously by the use of a receiver that is approximately optimal. An adaptive signal dot matrix is controlled by means of an associative network with recursive processing of the received signal in a detector. The detection algorithm aims at simulating distortions on the channel and provides an adaptation to the current interference situation even if the origin of interference is unknown. This provides a receiver that is more resistant to interference over the radio path. A received signal is divided in the time domain into blocks of a certain length, the blocks being used for simultaneous estimation of user data and channel parameters by recursive processing of each block. A quick adaptation of the receiver to the transmission propagation conditions is thus obtained.
