Wideband Non-Coherent Space-Time-Frequency Block Coding

Based on orthogonal frequency division multiplexing, this paper proposes non-coherent space-time-frequency grouping coding schemes in frequency-selective Multiple-Input and Multiple-Output(MIMO) antenna Rayleigh fading channels. Pair-wise error probability analysis show that combing subcarrier grouping with orthogonal space-time-frequency block coding, the proposed method can attain maximum spatial diversity and frequency diversity with low coding and decoding flexibility and neither the receiver nor the transmitter need knows the channel state information. The paper gives the code design criteria and simulation results, which confirm good performance of the proposed scheme in frequency-selective fading channels.
