Query: Design and Development of a Burst Acquisition System for Geosynchronous
  Satcom Channels   The key contribution of this work is to develop transmitter and receiver
algorithms in discrete-time for turbo- coded offset QPSK signals. The proposed
synchronization and detection techniques perform effectively at an SNR per bit
close to 1.5 dB, in the presence of a frequency offset as large as 30 % of the
symbol-rate and a clock offset of 25 ppm (parts per million). Due to the use of
up-sampling and matched filtering and a feedforward approach, the acquisition
time for clock recovery is just equal to the length of the preamble. The
carrier recovery algorithm does not exhibit any phase ambiguity, alleviating
the need for differentially encoding the data at the transmitter. The proposed
techniques are well suited for discrete-time implementation.
