摘要： here is provided a new multi-user receiver configuration technique which solves the problems of the user signal separation function of the multi-user receiver such as the interference canceller, decorrelator, and least square error detection. That is, there is provided a code-division multiplex signal decorrelation/identification method for realizing much more excellent performance than the aforementioned methods in the aspect of the power band amplitude product required for one-bit transfer as the evaluation reference of the CDMA method. A function for successively judging the best user is added to the conventional least square error detector MMSE-D shown by a dotted line in the block diagram of the successive detection type least square error detection method (SD-MMSE).

摘要： This invention provides techniques for a CDMA system having high spectrum efficiency with low transmit power. Each transmitter comprises means of selecting some core-sequences out of multiple sequences to make them convey plural data, means of producing an enveloped selected sequence with such a method as to arrange as guard sequences to a repeated sequence made by repeating each of the selected core-sequences, means of modulating a user specific orthogonal carrier frequency by the enveloped selected sequence to produce a transmit-symbol, and means of transmitting the transmit-symbols. And a receiver comprises means of demodulating a receive-symbol with one of the user specific carrier frequencies to produce a base-band receive-symbol, means of separating respective components corresponding to the sequences selected by the user, by analyzing the base-band receive-symbol with a matrix composed of a channel response vector from the user to the receiver to detect plural data on the components.
