Abstract:
In a communication system that uses time-division multiplex slots, a method of positioning synchronization and pilot symbols within the time-division multiplex slot comprising the steps of:defining a base pattern of synchronization, pilot, and data symbols for P sub-channels corresponding to a first channel bandwidth BP; replicating the base pattern N times to form an expanded pattern of synchronization, pilot, and data symbols for NÃ—P sub-channels corresponding to a second channel bandwidth BM being N times greater than the first channel bandwidth BP; subdividing an information signal into M bit streams, where M=NÃ—P; encoding each of the M bit streams into data symbols to form M symbol streams; and inserting the synchronization and pilot symbols into the M symbol streams yielding M composite symbol streams, the synchronization and pilot symbols being inserted at positions determined by the expanded pattern.
