1. In a wireless communications system, a method for preventing degradations in channel performance caused by puncturing information bits of uncertain sign into an otherwise continuous pilot channel comprising:

  • reconstructing a non-punctured pilot channel of predetermined sign from information symbols of uncertain sign punctured into a sequence of pilot channel symbols of predetermined sign to produce a continuous sequence of pilot symbols; and

    calculating a channel phase estimate by using only the reconstructed continuous sequence of pilot symbols.
