Title:
APPROXIMATION SCHEMES USING FUNCTIONAL FITTING IN CONSTELLATION SHAPING
Document Type and Number:
WIPO Patent Application WO/2024/016100
Kind Code:
A1
Abstract:
A wireless communication device configured with approximation schemes utilizing functional fitting in constellation shaping is disclosed. The device is configured to obtain subintervals over which to form piecewise polynomial approximations of a plurality of terms, obtain, utilizing the piecewise polynomial approximations of the plurality of terms, an approximation of a total number of first symbol sequences over a first alphabet having a first alphabet size, each respective symbol sequence of the total number of first symbol sequences having a first symbol sequence length and a first symbol sequence energy, obtain a bit sequence having a bit sequence length, encode the bit sequence, utilizing the approximation of the total number of first symbol sequences, to a second symbol sequence over a second alphabet having a second alphabet size, the second symbol sequence having a second symbol sequence length and a second symbol sequence energy, and transmit the second symbol sequence.
