1. A method for determining information element boundary of a signal, the signal having a plurality of information elements, each information element consisting of a group of codes, said method comprising steps of:

  • obtaining a symbol phase of the signal;

    calculating energies of the signal over a predetermined duration for a plurality of a first group of time units and dumping the energies into a first energy value;

    calculating energies of the signal over the predetermined duration for the plurality of a second group of time units and dumping the energies into a second energy value;

    comparing the first and second energy values; and

    determining which of the first and second groups of time units the information element boundary is in according to the comparing result of the first and second energy values and the symbol phase.
