A novel decoding scheme for DMPSK modulation based on look-up tables
Ruixi Zhu · 2014
A novel look-up table differential algorithm was proposed.Theory analysis showed that it could not only improve the hardware implementation,but also avoid the mathematic processing of the traditional differential modulation.Furthermore,an auto-updating radius sphere detection algorithm(AUR-SD)for multiple symbol differential detection(MSDD)to high complexity problems in the detection side was proposed.Simulation results showed that the algorithm had lower computational complexity and was much more approximated to the performance of the ML algorithm compared to the traditional width first sphere decoding detection algorithm.Therefore,it is an ideal choice in differential cooperative systems.
