ITERATIVE SUCCESSIVE INTERFERENCE CANCELLATION FOR ASYNCHRONOUS BANDWIDTH EFFICIENT DISTRIBUTED FDMA SYSTEMS
摘要
A block spread code division multiple access transmission system and a method of and receiver for cancelling interference in such a transmission system A block spread code division multiple access transmission system (100) comprises a plurality of user terminal transmitters (200) which are configured to: (i) apply precoding to each block of symbols by progressively rotating the phase of each block of symbols identically by a user-dependent amount; (ii) spread the precoded blocks in time or frequency using discrete Fourier transform spreading codes; and (iii) apply a guard interval in the form of a cyclic prefix. A receiver (300) uses a successive interference cancellation scheme to process the received signals. The successive interference cancellation scheme may be iterative.
