Abstract
We derive a novel block differential codec to bypass estimation of rapidly fading channels. Based on a basis expansion model for time-varying channels, our differential design is easy to implement, and achieves the maximum possible Doppler diversity. Combined with a group partitioning scheme, the differential scheme provides also flexibility to tradeoff decoding complexity with performance. Simulation results corroborate our theoretical analysis.
