ABSTRACT:
A wireless communication network that implements Circular Simplex Turbo Block Coded Modulation (“CSTBCM”) Forward Error Correction (“FEC”), randomization and Wavelet Packet Modulation (“WPM”) is provided. The network includes a transmitter that uses an adaptive tree structure. The tree structure is pruned to avoid known signal impediments by first determining the best uniform level and then tuning in the forward direction and in the reverse direction. The network also includes a receiver that implements a maximum likelihood decision directed (“MLDD”) synchronization scheme. The synchronization scheme is pulse shape independent and non-data aided.
