It is known that multiple trellis coded PSK (MTC-PSK) can achieve larger performance gain, and trellis coded continuous phase modulation (CPM) combined with Multi-h scheme can also achieve good power bandwidth tradeoffs. In this paper, we propose multiple trellis coded CPFSK (MTC-CPFSK), combined with Multi-h scheme to achieve further coding gain over MTC-PSK. We find that MTC-CPFSK with Multi-h scheme achieves lager squared minimum Euclidean distance and diminishes the number of merge events up to 10Ts depth in the state trellis. We also find that the number of merge events whose squared Euclidean distance is near to squared minimum Euclidean distance may be increased by employing MTC-CPFSK, compared to TC-CPFSK.
