METHOD AND DEVICE FOR EFFICIENT MULTI-USER MULTI-VARIANT PARALLEL TRANSMISSION

摘要

The invention discloses a method and a device for efficient multi-user multi-variant parallel transmission. The method involves processing multi-variant coding over GF(q) on each data symbol of user data symbols to obtain corresponding multiple multi-variant symbols. Multiple bits corresponding to each multi-variant symbol are partitioned to obtain multi-layer bit streams. Each multi-layer bit stream is modulated to map with corresponding constellation points to obtain modulation symbols of users. Then precoding of the modulation symbols is processed and outputted to corresponding transmitters of multiple antennas.
