Preamble acquisition without second order timing loops

A method for adjusting a clock, comprising:

• obtaining a first plurality of samples and a second plurality of samples associated with a preamble portion of a data packet, wherein the first plurality of samples and the second plurality of samples are sampled using a clock;
• using a processor to determine a first intermediate value based at least in part on the first plurality of samples;
• using the processor to determine a second intermediate value based at least in part on the second plurality of samples;
• using the processor to determine an ending value associated with an end of the preamble portion based at least in part on the first intermediate value and the second intermediate value;
• and
• adjusting the clock based at least in part on the ending value without use of a second order timing loop.

A computer program product for adjusting a clock, the computer program product being embodied in a computer readable storage medium and comprising computer instructions for:

• obtaining a first plurality of samples and a second plurality of samples associated with a preamble portion of a data packet, wherein the first plurality of samples and the second plurality of samples are sampled using a clock;
• determining a first intermediate value based at least in part on the first plurality of samples;
• determining a second intermediate value based at least in part on the second plurality of samples;
• determining an ending value associated with an end of the preamble portion based at least in part on the first intermediate value and the second intermediate value;
• and
• adjusting the clock based at least in part on the ending value without use of a second order timing loop.
