BURST DEMODULATOR

Published: March 4, 2010

Assignee:  COMTECH EF DATA CORP.

Inventors:  Eymann; Steven; (Phoenix, AZ) ; Reum; Phil; (Tempe, AZ)

Abstract:  A burst demodulator. Implementations may include a first frequency estimating module adapted to remove a first frequency offset from a plurality of data samples. A second frequency estimating module may be coupled with the first frequency estimating module and may be adapted to remove a second frequency offset from the plurality of data samples. A third frequency estimating module may be coupled with the second frequency estimating module and may be adapted to remove a third frequency offset from the plurality of data samples. A clock phase estimating module may be coupled with the third frequency estimating module and may be adapted to calculate a clock phase offset value, select one or more coefficients for a finite impulse response (FIR) filter, and process the plurality of data samples with the FIR filter. A data processing module may be adapted to recover the data included in the plurality of data samples.
