Abstract
A method for communication includes allocating, in a multiple-access communication system (20) that uses multiple subcarriers, first subcarriers to a first communication terminal for transmitting first data, and second subcarriers to a second communication terminal for transmitting second data. The first communication terminal is assigned to modulate the first data onto at least some of the first subcarriers using a first multi-carrier modulation scheme, to produce a first signal. The second communication terminal is assigned to modulate the second data onto at least some of the second subcarriers using a second multi-carrier modulation scheme, which has a reduced peak-to-average power ratio (PAPR) relative to the first multi-carrier modulation scheme, to produce a second signal. Simultaneous communication is carried out with the first and second communication terminals by simultaneously receiving the first and second signals over the first and second subcarriers.
