Improving the spectral efficiency of FDM-CPM systems through packing and multiuser processing

Amina Piemontese, Nicolo Mazzali, Giulio Colavolpe
2010 2010 5th Advanced Satellite Multimedia Systems Conference and the 11th Signal Processing for Space Communications Workshop  
In frequency division multiplexed (FDM) systems, spectral efficiency can be increased by reducing the spacing between two adjacent channels, thus increasing the relevant interference and possibly accounting  ...  In this paper, we consider a FDM system where each user employs a continuous phase modulation (CPM), serially concatenated with an outer code through an interleaver, and iterative detection/decoding.  ...  The analysis is based on the computation of information rate (IR) and spectral efficiency (SE) of FDM-CPM systems and is an extension of the approach described in [4] .  ...

Frequency Packing and Multiuser Detection for CPMs: How to Improve the Spectral Efficiency of DVB-RCS2 Systems

Amina Piemontese, Alexandre Graell i Amat, Giulio Colavolpe
2013 IEEE Wireless Communications Letters  
We describe a framework for computing the information rate (IR) and the SE of such systems, and use it for optimizing the channel spacing between adjacent users and the CPM phase response.  ...  We consider a frequency division multiplexed system where each user adopts a continuous phase modulation (CPM) and multiuser detection is employed at the receiver side.  ...  Frequency Packing and Multiuser Detection for CPMs: How to Improve the Spectral Efficiency of DVB-RCS2 Systems Amina Piemontese, Member, IEEE, Alexandre Graell i Amat, Senior Member, IEEE, and Giulio Colavolpe  ...
