In this paper a new perspective on modeling of transient phenomena in the context of sinusoidal audio modeling and coding is presented. In our approach the task of nding time-varying amplitudes for sinusoidal models is viewed as an AM demodulation problem. A general perfect reconstruction framework for amplitude modulated sinusoids is introduced and model reductions lead to a model for audio co...

A multiple-input multiple-output (MIMO) wireless transmission system with continuous phase modulation (CPM) is considered. A novel MIMO CPM receiver with incoherent modulation is presented. The incoherent demodulation of CPM allows an uncomplicated handling of a frequency offset compared to coherent approaches requiring exact knowledge of the carrier frequency. Blind signal separation (BSS) is ...

We consider a signaling format where information is modulated via a superposition of independent data streams. Each data stream is formed by replication and permutation of encoded information bits. The relations between data bits and modulation symbols transmitted over the channel can be represented in the form of a sparse graph. The modulated streams are transmitted with a time offset enabling...

In this paper, we focus our attention on blind demodulation for multi-carrier modulation in the context of radio surveillance and military applications. We present a blind demodulation technique for CP-OFDM and ZP-OFDM transmission over frequency selective channels. The technique exploits the cyclic prefix or zero padding structure of the transmitted signal to estimate the parameters and to dem...
