Synchronisation Techniques. Edition No. 1
VDM Publishing House, October 2008, Pages: 196
In systems with highly efficient turbo-codes, where
the operating SNR may be as low as 1-2 dB, excellent
estimation accuracy for synchronisation parameters
is required. However, in such conditions
conventional non-data-aided synchronisation
techniques become difficult due to the low SNRs. In
addition, to achieve a high efficiency, it is
desirable to recovery synchronisation from received
data signals without using preambles. This book
describes a novel concept, which is called a priori
probability aided synchronisation. This concept fits
particularly well with the iterative turbo decoder,
but it will also be applicable with other types of
code. The proposed synchronisation operates
iteratively and jointly with the turbo decoding,
rather than separately prior to the decoding. This
allows a successive refinement of synchronisation
and provides reliable estimation and robust data
decoding against a wide range of synchronisation
offsets. It is shown that remarkable
performance approaching that of the data-aided
techniques can be achieved using blind
synchronisation at low SNRs.
