Title:
DEMAPPING FOR HIERARCHICAL QUADRATURE AMPLITUDE MODULATION
Document Type and Number:
WIPO Patent Application WO/2013/130987
Kind Code:
A3
Abstract:
A method and system for demapping a hierarchical signal is disclosed. The method includes receiving a hierarchical signal comprising first and second encoded, modulated signals. A conditional probability relating to the structure of the second encoded, modulated signal is determined. The hierarchical signal is demodulated using the conditional probability to generate a first encoded data stream. The first encoded data stream is decoded to recover information bits.
