摘要： A method of operation of a communication system includes: receiving an input signal having an input primary codeword and an input parallel codeword; calculating a primary codeword signal by removing a parallel soft information average of the input parallel codeword from the input signal; filtering a residual parallel interference of the input parallel codeword from the primary codeword signal with a primary whitening filter to generate a primary codeword estimation of the input primary codeword; and calculating a primary detected soft information for the primary codeword estimation for communicating with a device.

摘要： Apparatuses, systems, and methods are described for power allocation in a superposition multiple access communication system capable of using non-uniform joint constellations or super-constellations. In one method, the conditional probability of a correctly-received symbol and a normalized weighting coefficient is calculated for each receiver and then the sum of weighted efficiencies is calculated. The optimal power allocation is determined for each receiver by maximizing the sum of weighted spectral efficiencies.
