Distributed STF coding for C-OFDM systems
Xin Xu, Song Zhiqun, Weiwei Yang, Heng Yu Wu, Xiaoning Liu · 2009
A distributed space-time-frequency (STF) coding scheme is proposed for cooperative OFDM (C-OFDM) systems with three terminals over quasi-static frequency-selective Rayleigh fading channels. The outage probability performance is derived and its tight closed-form lower bound is presented. Asymptotic analysis indicates that the proposed scheme can achieve both spatial and multipath (frequency) diversity. Simulation results confirm the previously introduced theoretical analysis.
