Symbol Block Construction for Frequency Domain Equalization of Multi-H CPM
This paper considers the construction of a symbol block to generate a cyclic multi-h Continuous Phase Modulated (CPM) signal so as to permit Frequency Domain Equalization (FDE) at the receiver. Like single-h CPM, the memory inherent in a multi-h CPM waveform requires an intra-fix in each transmitted block. The authors propose a novel procedure that determines the intra-fix symbols, such that the intra-fix length is minimized. The constraints on the required intra-fix symbols are shown to form a set of Linear Diophantine Equations (LDEs). The proposed procedure is applied to a dual-h CPM scheme.
