This paper examines the performance of some recently proposed Space-time coding and signal processing techniques when applied to Orthogonal Frequency Division Multiplexing (OFDM) in Multiple Input Multiple Output (MIMO) configuration. Performance results using statistical multi-element channel models are compared with those using state-of-the-art MIMO channel measurements. The paper investigates Space-Frequency Trellis Coded Modulations (SFTCM) along with a number of BLAST detection algorithms: ML, Successive Interference Cancellation (original BLAST); linear ZF; ZF-ML hybrid. The wideband MIMO measurements utilised here have been taken using a customised MIMO vector channel sounder operating in the 5.2 GHz band with 120 MHz of bandwidth. The primary focus of this paper is to assess the robustness and performance loss of the different spacetime techniques when operating in real (measured) scenarios.
