GMSK METHOD AND APPARATUS FOR GENERATING PREAMBLE SEQUENCE IN GMSK COMMUNICATION SYSTEM

摘要

Provided is a method for generating a preamble sequence in a GMSK communication system. According to an embodiment of the present invention, the method comprises the steps of: generating an expanded Hadamard matrix by expanding an initial Hadamard matrix; selecting a plurality of selected Hadamard sequence groups which are groups of Hadamard sequences maintaining orthogonality between different Hadamard sequences of a plurality of the Hadamard sequences based on the expanded Hadamard matrix; and generating a preamble sequence based on the plurality of selected Hadamard sequence groups. Accordingly, the method is provided for generating a preamble sequence enabling beam tracking towards a plurality of communication apparatus in a GMSK communication system based on the Hadamard sequence.
