Patent ID: 11848809

Abstract:
A profile optimizing method is provided for a transmission of active subcarriers over a channel to user devices. The method includes steps of (i) obtaining a symbol mapping architecture for the set of profiles, (ii) calculating, from the symbol mapping architecture, a plurality of mapping orders for the set of profiles different from the logical order, (iii) determining, from the calculated plurality of mapping orders, a particular mapping order having a higher spectral efficiency than the logical order, (iv) reordering the respective codewords of the set of profiles to correspond to the particular mapping order, (v) re-mapping the symbol mapping architecture to a number of symbols corresponding to the reordered codewords, and (vi) transmitting the symbols to the population of user devices. The symbol mapping architecture includes a codeword for each profile of the set of profiles, and maps the codewords to a different number by logical order.
