Abstract:
1. A method for detecting user transmitted symbols encoded in physical user waveforms comprising decomposing each of one or more physical user waveforms into one or more respective virtual user waveforms, each virtual user waveform representing at least a portion of a symbol encoded in the respective physical user waveform, determining cross-correlations among the virtual user waveforms as a function of one of more characteristics of the respective physical user waveforms, the determining step includes generating a first matrix that stores the cross-correlations among the virtual user waveforms, generating, from the first matrix, a second matrix representing a cross-correlation of the physical user waveforms, generating estimates of the symbols encoded in the physical user waveforms as a function of the cross-correlations, the step of generating the estimates of the symbols includes generating those estimates from the second matrix.
