1. A transmitter comprising:

  • a combiner configured to introduce pilot signals into a stream of user data as a locally unique time-frequency shift of a time frequency plane array, wherein the time frequency plane array is generated from a regular spaced base signal which is hopped using a hopping sequence, and wherein the locally unique time-frequency shift of the time frequency plane array involves a time shift and a frequency shift,a channel transmission element configured to apply the stream of user data with the introduced pilot signals onto a channel,a memory configured to store the hopping sequence upon which the time frequency plane array is based, the hopping sequence being configured in the memory so that any two time-frequency shifts of the time frequency plane array has a predetermined number of coincidences.
