1. A method for co-existence of an orthogonal frequency division multiple access (OFDMA) transceiver with a synchronous frame-based transmitter comprising:

  • receiving a transmission enable (TXE) signal indicating that the OFDMA transceiver is transmitting;

    determining, from the TXE signal, an estimated transmission enable (TXE′

    ) signal, the TXE′

    signal being a prediction of the future TXE signal and indicating when the OFDMA transceiver is expected to be transmitting;

    sending the TXE′

    signal to the synchronous frame-based transmitter to shut down the synchronous frame-based transmitter when a transmission is expected to be sent from the OFDMA transceiver.
