Patent ID: 6999446

Claim:
A method for operating a wireless communications system, comprising: transmitting a waveform, the waveform comprising a plurality of repeating frames each comprising x header training base symbols in a header training symbol field (TH) and y tail training base symbols in a tail training symbol field (TT); and receiving a frame; where the received frame functions as one of a plurality of different types of frames depending on the content of at least TT wherein a frame function as one of a normal traffic frame and a termination frame, wherein the step of receiving includes a step identifying the frame as to a type of frame by examining at least the content of TT, and wherein for the case of the repeating frames being of the normal frame type, the contents of the THs and of the TTs is the same across the repeating normal frames, the normal frame THs and TTs are not error correction encoded, and the normal frame THs and TTs are used by receiver circuitry at least for one of frame synchronization, equalizer training and AGC training purposes.
