Modulating codes on the basis of modified Walsh functions

Walsh functions are widely used for coding of information transmitted in discrete transceiving systems. Their use is explained by the possibility of error detection and correction due to a large code distance. One of the disadvantages of Walsh functions is the occurrence of combinations coinciding with code words of the origin collection. This does not allow the use these functions for receiver framing. Modified Walsh functions, used in MBOK modulation, as well as complementary codes of CCK modulation, have the same disadvantage. The aim of the research was to create a set of modulating codes for wide-band communication systems with quadrature phase modulation, which would allow one to conduct receiver framing by the input code chain.
