Communication method and device

摘要

The present invention relates to the field of communication and transmission of signals. In particular, the present invention relates to a new communication and/or modulation method. The present invention also relates to improving channel occupancy. The present specification discloses the adoption of phase transitions/changes in a manner that indicates a code by virtue of their position (timing) in the communication. This is referred to as Phase Position Modulation.

1. A method of modulating a signal, the method comprising:
determining a predefined time period during which a portion of the signal is able to be encoded, the predefined time period comprising a plurality of time intervals; encoding the signal in association with at least one time interval of the plurality of time intervals, the encoding providing modulation symbols associated with the predefined time period; and suppressing, in a data sequence of the encoded signal, a transition of any modulation symbol having only one transition and representing at least one of an amplitude change and a phase change in a first time interval of the predefined time period except where there are two or more sequential modulation symbols in the data sequence of the encoded signal that have only one transition and represent at least one of an amplitude change and a phase change in the first time interval in which case only the transition of the first one of the two or more sequential modulation symbols is suppressed.
