In this paper, the authors propose Pre-DFT processing for MIMO OFDM with space time frequency coding. For the application such as high speed computer network, multimedia services and the demand of flexible drive requires a necessity of the broadband wireless communication systems thus the available frequency spectrum is insufficient for the future systems. To accomplish the demand, spectral efficiency must be enhanced in order to increases link throughput and network capacity. A promising approach is to use multiple antennas at both transmitter and receiver i.e., a Multiple-Input Multiple-Output (MIMO) system.
