UNIPOLAR BINARY SEQUENCES HAVING IMPROVED NON-PERIODIC CORRELATION BEHAVIOUR FOR UNSYNCHRONISED TSMA SYSTEMS

摘要

Embodiments of the invention relate to a method for generating a hopping pattern for transmitting a plurality of sub-data packets in a communications system. The method comprises a step of deriving a hopping pattern from a binary sequence, wherein an autocorrelation function of the binary sequence has autocorrelation secondary maxima of a specified maximum value. The method also comprises a step of determining a maximum sub-data packet length for the plurality of sub-data packets on the basis of a total transmission duration of the plurality of sub-data packets as specified by the hopping pattern and on the basis of a minimum value of a difference sequence of a sorted difference number series derived from the binary sequence.
