ABSTRACT:
Systems and methods are provided for signaling control information in a communication of data. The method includes overwriting a portion of a frame in a sequence of frames with control information. The control information has a low bit size, and the overwriting is performed at a frequency of less than about 20% of the frames. The system includes a spread spectrum transmitter that includes a channel coder, an interleaver and framer unit, and an insertion unit. The insertion unit is configured to overwrite a portion of a frame in a sequence of frames with control information and is further configured to overwrite at a frequency of less than about 20% of the frames.
