Abstract :
Aimed at single channel mixing signals with the same modulating parameters, separability problem for single channel blind source separation (SCBSS) in satellite flat fading channels is treated in this paper. Firstly, on the basis of single channel mixing model, multi-input single-output (MISO) model of the problem is transformed into multi-input multi-output (MIMO) model using fractionally spaced sampling theory. Furthermore, from the influence of transmitting channel on the structure of mixing matrix, blind separability of single channel mixing signals is discussed. Based on this, blind separation conditions are given. Moreover, some simple examples are presented to interpret the results.
