Spectral-efficiency comparison of different multiple-access schemes under a generalized framework


Based on multicarrier communications principles, this paper compares the spectral-efficiency (SE) of a range of multiple-access (MA) schemes via a generalized framework referred to as the generalized code-division multiple-access (GCDMA). As detailed in the paper, by assuming different classes of spreading codes, the GCDMA can be readily configured to form… (More)
