A wireless MIMO CPM system with blind signal separation for incoherent demodulation

[摘要] A multiple-input multiple-output (MIMO) wireless transmission system withcontinuous phase modulation (CPM) is considered. A novel MIMO CPM receiverwith incoherent modulation is presented. The incoherent demodulation of CPMallows an uncomplicated handling of a frequency offset compared to coherentapproaches requiring exact knowledge of the carrier frequency. Blind signalseparation (BSS) is applied in the proposed MIMO CPM receiver to separate thesignals without any knowledge of the MIMO channel. The BSS permits thedemodulation of each separated signal by an incoherent CPM demodulator. Forbandwidth efficient transmission partial response CPM and non-binarymodulation is applied. The applicability of the proposed system is verifiedby simulation results.
