“…In this scenario, we consider only noncoherent detection following the equaliser due to its inherent robustness to remnant frequency and phase offsets. The algorithms used to estimate the unknown synchronisation parameters are detailed in [11] to which the reader is referred for a more thorough analysis. Figure 6 shows the bit error rate curves for one pass through the noncoherent receiver with and without channel equalisation and receiver synchronisation enabled.…”

Modern spectrally efficient continuous phase modulation (CPM) waveforms offer attractive properties for narrowband tactical communications operating in VHF/UHF 30-400MHz bands. These waveforms exhibit robustness to a significant amount of intersymbol interference, due to multipath propagation, when iterative receivers are used for demodulation and decoding. However, certain propagation characteristics encountered in mountainous or coastal terrains may represent exceptionally challenging multipath environments. In these scenarios, the use of simple types of channel equalisation schemes, with an iterative CPM receiver, is demonstrated to alleviate the detrimental impact of multipath propagation. The combined effect of equalisation and iterative demodulation and decoding is investigated as a method to operate under these conditions.

“…In [3], a new optimal synchronization scheme has been developed for AWGN channels (including preamble design) has been proposed to achieve the Cramer Rao Bound. In its equalization scheme, [4] uses a Thanks to Thales Alenia Space and the CNES agency (French Space Agency) for funding method suited to AWGN channel for carrier recovery [5]. In the context of equalization, channel estimation has been studied in [6,7].…”

In this paper, we present a new data-aided carrier-recovery method for Continuous Phase Modulation (CPM) signals over frequency-selective channels. We first present a linear model of the received signal based on Mengali representation over selective channels and show how to use it to perform joint channel and carrier-frequency estimation. We also derive a low-complexity version of the estimator. Simulation results show that this method performs better than the optimal method suited to the Additive White Gaussian Noise (AWGN) channels.
