Various aspects of an approach for acquiring sequences such as balanced Hamming weight preamble sequences are described herein. The approach provides for the acquisition of preamble sequences base on energy accumulation. The approach includes 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; selecting, as a candidate, one hypothesis from the plurality of synchronization hypotheses including a maximum associated metric. The approach may further include determining a boundary in the sequence of transmitted symbols based on a correlation property of the sequence of transmitted symbols. The second location includes a predetermined offset from the first location configured to provide enhanced interference immunity.
