Abstract
Methods and apparatus for receiving a signal having a intermediate frequency (IF), sampling the IF signal at a selected sampling frequency, correlating the sampled IF signal with a preamble signal, determining a correlation peak for the correlated signals, identifying chips of the preamble signal based upon the correlation peak, and decoding the IF signal to obtain and store information encoded in the IF signal.
Claims18
A method, comprising:
- receiving a signal having a intermediate frequency (IF);
- sampling the IF signal at a selected sampling frequency;
- correlating, using a computer processor, the sampled IF signal with a preamble signal;
- determining a correlation peak for the correlated signals;
- identifying chips of the preamble signal based upon the correlation peak;
- and
- decoding the IF signal to obtain and store information encoded in the IF signal.
4 more elements
A system, comprising:
- a receiver to receive an IF signal;
- a preamble correlator to correlate the received IF signal and a preamble signal to determine correlation peaks for identifying chips of the preamble signal based upon the correlation peak to enable decoding of the IF signal to obtain and store information encoded in the IF signal.
A method comprising:
- performing MSK demodulation of a signal directly from an IF signal without conversion to base-band signals.
