Method for Generating a Data Block for Transmission Using a Cpm Scheme

A method for generating a data block for transmission using a continuous phase modulation scheme is disclosed. In one aspect, the method includes inserting payload data in the data block, the payload data having a plurality of payload symbols, each involving an state change in a continuous phase modulation waveform generated from the data block in one of two opposite directions. It may include inserting state compensation data in the data block for cancelling out the state changes, such that the waveform has an end state at the end of the data block equal to a begin state at the beginning of the data block. The state compensation data is determined by determining from the state changes an overall state change caused by the payload data over the waveform and by selecting a set of compensation symbols for the state compensation data on the basis of the overall state change.
