Abstract
In this letter, we design and analyze a novel differentially coherent decision feedback structure for differentially bi-orthogonal code (DBOC). Proposed detector using decision feedback and partially maximum likelihood sequence estimation (DF-PMSE) can be applied to the DBOC detector irrespective of bi-orthogonal code length. Simulation and analyzed results show that the PER performance of the proposed detector is almost the same as that of the coherent detector for the various case of bi-orthogonal code length.
