ABSTRACT:
A transmitter device comprises an OFDM transmission unit, a MC-CDMA transmission unit, and a control unit for selecting either the OFDM transmission unit or the MC-CDMA transmission unit at slot time assigned to a receiver device in response to propagation conditions for the receiver device. The propagation conditions are a distance from the receiver device and a CINR.
