Abstract

We present an orthogonal frequency-division multiplexing (OFDM) system with bit-interleaved space-frequency coded modulation for frequency selective fading channels employing multiple transmit and receive antenna. OFDM is used to transform a frequency selective fading channel into multiple flat fading channels, and space-frequency trellis coding combined with bit-interleaving is used to exploit space and frequency diversity. The performance of such an approach is evaluated by analytical bounds and simulation. With the use of space-frequency coding and BICM, we can provide increased rates and also improved performance by means of increased diversity.
