Abstract :
The constellation rotation and cyclic Q-delay technique has been adopted in the second generation terrestrial digital video broadcasting (DVB-T2) standard. It improves the performance under fading channels, but introduces serious complexity problems in the hardware implementation of the demapper. Presented is a simplified demapper scheme that reduces up to 31% the number of required operations with almost no performance degradation.
