Systems and methods for implementing receiver transparent q-mode

Abstract

In a receiver transparent Q-mode, i.e., a Q-mode that is only implemented by a transmitter, the receiver is unaware of the Q-mode state of the transmitter. In this type of Q-mode configuration, the transmitter could enter and exit Q-mode as desired while the receiver, could, for example, continue to function as if operating normally, such as in “showtime.” Through this approach, it is not necessary for the receiver to detect the transmitter's entry and exit of Q-mode.

1 . A method for a transmitter to enter a Q-mode comprising:
 receiving an all zeros bit pattern;   transmitting a Q-mode symbol; and   entering a Q-mode, wherein the entry and exit of the Q-mode is independent of an operational state of a receiver.
