Abstract :
We consider the transmission of space-time block codes (STBC) over doubly-selective channels, which are encountered in highly mobile environments or high-frequency (HF) communications. In particular, we propose two extensions of time-reversal STBC with superior performance under these fast-fading conditions, and compare these schemes for various decision-feedback equalizers. The tradeoffs between performance and complexity are illustrated, and simulation results for the severely doubly-selective HF-channel corroborate our analysis
