Method and apparatus for efficient acquisition of preambles with enhanced interference mitigation

An apparatus for preamble acquisition comprising:

• a processor;
• and
• a memory coupled to the processor comprising instructions executable by the processor for:
• creating a plurality of synchronization hypotheses, with each hypothesis being created based on energies sampled at a first location and a second location in a plurality of locations associated with a sequence of transmitted symbols;
• calculating a plurality of metrics based on the plurality of synchronization hypotheses, wherein each metric is associated with a hypothesis;
• and,
• selecting, as a candidate, one hypothesis from the plurality of synchronization hypotheses comprising a maximum associated metric.
