Multicarrier multiple access is sum-rate optimal for block transmissions over circulant ISI channels
13 years 7 months ago
Abstract--Multicarrier multiple access with channel knowledge and prescribed power at the transmitters is shown to maximize the sum-rate for circulant intersymbol-interference (ISI...
