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. We 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.
