Sliding-Spectrum Calculation Algorithm Intended to Detect OFDM Signals in Synchronization Systems

Abstract

The results concerning the development and investigation of the algorithms for incoherent detection of orthogonal frequency-division multiplexing signal preambles, which are used to synchronize processes in synchronous systems of discrete data transmission over single- and multibeam channels, are presented. It is demonstrated that the developed detection procedures rely on the stable algorithm of calculation of the sliding spectrum and are alternative to the detection technique based on the fast spectral transform in the Fourier basis with respect to their throughput.
