Digital Mobile Radio (DMR) is the latest digital trunking communication standard developed by European Telecommunications Standards Institute (ETSI). In this standard, the modulation waveform of 4CPFSK is used to enhance the spectrum efficiency. While the conventional symbol by symbol detection shows relatively poor performance for these signals, the multiple symbol detection algorithm proposed in...
It is known that multi-symbol detection shows good bit error rate performance for estimation of continuous phase modulation (CPM) signals, yet the complexity of its receiver structures goes exponentially with the increasing length of the pulse-shaping filter and observation window length. A new simple non-coherent trellis receiver for CPM signals is proposed in this paper. Similar to the simple coherent...
