Data is transmitted during a transmission time interval using an available frequency bandwidth. Blocks of data to be transmitted at different power levels are identified. Multiple portions of the data blocks are distributed for transmission at different frequencies so that data blocks with higher power levels are distributed more toward the center of the determined frequency bandwidth than data blocks with lower power levels. The distributing of data block portions reduces the power of intermodulation products occurring outside the determined frequency bandwidth caused by radio frequency signals carrying the distributed data block portions fed through a non-linear power amplifier. It also reduces peaks in the power of the intermodulation products.
