Abstract

A method and apparatus for processing data to be communicated between an implantable medical device and an external medical device to improve detectability of communication errors. An encoded block of data including message data and redundant data is processed by converting alternating data values of either the message data or the redundant data to respective complement data values. The altered block of data is communicated using relative pulse position modulation. The combination of alternating original and complement data with relative pulse position modulation (RPPM) takes advantage of the opposing adjacent errors characteristic of RPPM to decrease the probability of communication errors occurring in combinations that are undetectable by the decoding of the block of data.
