APPARATUS FOR INITIAL SYNCHRONISATION IN CODE-TIME MULTIPLEXED NETWORKS Russian patent published in 2011 - IPC H04L7/10 

FIELD: information technology.

SUBSTANCE: apparatus for initial synchronisation in code-time multiplexed networks has two quadrature channels, each having a multiplier, a band-pass filter, an analogue-to-digital converter, a digital matched filter, a device for selecting maximum signal, a selector, an averager, two squaring device, as well as a π/2 phase changer, a heterodyne, three adders, a memory device, a clock pulse generator, a pseudorandom sequence generator, two multipliers, a down counter, a frequency divider, buffer register, a threshold device, a digitiser, a device for measuring time scale shift, a threshold adder, a relative phase telegraphy detector, five rectifiers, a digital matched marker filter, as well as a threshold marker device and corresponding connections between them.

EFFECT: synchronising a receiver through reliable detection of a one-time transmitted marker and preambles based on information contained in the preamble on the position of the marker relative the preamble.
