Abstract

This paper describes the hierarchical woven coded CPFSK (hWCCPFSK), is a serial concatenation of different outer convolutional codes and inner continuous phase frequency shift keying (CPFSK). Classical woven coded CPFSK (cWCCPFSK) has identical outer convolutional codes. We show that with a proper choice of the outer codes, hWCCPFSK has better decoding behaviour but cWCCPFSK has larger free distance. Hence, hWCCPFSK performes better in the waterfall region of the bit error rate curves, while cWCCPFSK is better in the error floor region.
