Abstract

The invention provides a data processing method for an interleave division multiple-access (IDMA) transmitter system, an interleave division multiplexing transmitter and a transmitter. The IDMA transmitter system mainly comprises a plurality of transmitters, each of which comprises inserted prefix units and interleavers; each transmitter is identified according to the difference of the interleavers; no IFFT unit with a same mapping mode is arranged between the interleaver and the inserted prefix unit of each transmitter. By utilizing the method of the invention, the complexity of the IDMA system is effectively reduced and the system has the advantages of comparatively low peak-to-average ratio and the insensitivity to frequency deviation, etc.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an interleaving multiple address transmitter system, an interleaving multiplexing transmitter and a data processing method. Background technique [0002] Interleaving multiple access is a multi-user detection technology and a brand new multiple access technology. Interleaved multiple access is different from the existing FDMA (Frequency Division Multiple Access, Frequency Division Multiple Access), TDMA (Time Division Multiple Access, Time Division Multiple Access), CDMA (Code Division Multiple Access, Code Division Multiple Access) and OFDMA (Orthogonal Frequency Division Multiple Access) Access, Orthogonal Frequency Division Multiple Access) and other multiple access methods, interleaved multiple access uses different interleavers to distinguish different users, which can effectively eliminate multiple access interference and improve system capacity. [0003] At present, ...
