Rapidly fading channels provide Doppler-induced diversity, but are also challenging to estimate. To by-pass channel estimation, we derive a novel block differential codec. Relying on a basis expansion model for time-varying channels, our block differential design is easy to implement, and achieves the maximum possible Doppler diversity. Simulation results corroborate our theoretical analysis.
