Single carrier transmission with a frequency domain equalization (SCFDE) is combined to a MIMO system and extended to multiuser techniques in CDMA. We also compare the overall system in terms of modulation format, such as constant phase modulations. The overall system features constant envelope transmit signals, which are immune to the non-linearity of the power amplifiers, a high spectral efficiency and a low complex equalization process at the receiver for multiuser environments. After a description of the concepts we show simulation results for SCFDE adapted to the MIMO-extended UMTS-TDD down link
