System and method for inserting pilot symbols in continuous phase modudlation systems

A method for transmitting digital information using a continuous phase modulation scheme, the method comprising:

• obtaining a data frame requiring a number of phase reference points to allow a receiving device to sufficiently estimate effects of a channel on the data frame during transmission;
• selecting a first phase reference point in the data frame;
• generating a set of pilot symbols for a second phase reference point in the data frame, the set of pilot symbols including at least one pilot symbol having a value calculated to set the second phase reference point to a certain phase state;
• and
• inserting the set of pilot symbols into the data frame,
• wherein the certain phase state is determined based on the phase state of the first phase reference point.

A system for communicating digital information using a continuous phase modulation scheme comprising:

• a precoder for receiving a sequence of data bits, mapping the sequence of data bits into data symbols and organizing the data symbols into one or more data frames;
• a pilot symbol generator for generating and inserting pilot symbols into each data frame such that each data frame includes an x number of phase reference points set to a phase state using an x-1 number of pilot symbol sets;
• and
• a continuous phase modulator for modulating and transmitting each data frame over a communication channel.
