Synchronization using training sequences with a periodical structure

摘要

The receiver has a unit (17) for compensating a received signal with a frequency offset from a frequency offset estimation unit to form a compensated received signal where the frequency offset estimation unit includes a part for determining phase shift. A determining unit obtains a timing reference for the received signal by cross-correlation (19) of the compensated received signal with a known training sequence. Independent claims are also included for the following: (a) an orthogonal frequency division multiplex (OFDM) telecommunication system including the receiver (b) a method for processing a received signal including a carrier modulated with a known training sequence (c) a method for obtaining timing reference from a received signal including a carrier modulated with a known training sequence.
