A technique for improving multiple-channel multi-tone transmissions is disclosed. According to one particular embodiment, a method for transmitting data over at least two bonded channels is provided, wherein each of the at least two bonded channels comprises a plurality of tones. The method may comprise: transmitting a first symbol stream over a first tone in a first bonded channel and over a second tone in a second bonded channel, wherein the first tone is bonded to the second tone, and the transmissions over the first tone and the second tone are substantially in parallel; transmitting a second symbol stream over a third tone in the first bonded channel; and transmitting a third symbol stream over a fourth tone in the second bonded channel, wherein the third tone is bonded to the fourth tone, and the transmissions of the second symbol stream and the third symbol stream are substantially in parallel.
