4. The method of claim 1 , wherein the receiver monitors the received signal when the receiver has information indicating that the signal of interest is not present.

5. The method of claim 1 , wherein the receiver monitors the received signal when the receiver has information indicating that the interfering signal is not present.

6. The method of claim 1 , wherein selecting the desired transmit time delay further comprises selecting the desired transmit time delay to reduce a number of the multi-carrier symbols of the signal of interest that are impacted by the interfering signal.

determining, by the receiver, an interference signal clock offset relative to a receiver clock by decoding preamble information of packets of the interfering signal;

determining, by the receiver, a signal of interest clock offset relative to the receiver clock by decoding the preamble information of packets of the signal of interest; and

estimating the clock timing offset by a difference between the interference signal clock offset and the signal of interest clock offset.

9. The method of claim 1 , wherein the receiver provides the transmitter with the desired transmit time delay by adjusting an acknowledgement time delay of acknowledgements to received packets of the signal of interest.

10. The method of claim 9 , further comprising:

estimating, by the receiver, a clock timing offset between the signal of interest and the interfering signal; and

adjusting, by the receiver, the acknowledgement time delay of the acknowledgements, wherein adjusting the acknowledgement time delay of the acknowledgements is based on the clock timing offset.

11. The method of claim 1 , further comprising providing the transmitter of the signal of interest with the desired transmit time delay.

12. The method of claim 11 , wherein the receiver which provides a rate to the transmitter with the desired transmit time delay is dependent on how rapidly the desired transmit time delay varies with time.

13. The method of claim 11 , further comprising filtering by the receiver, the desired transmit time delay and providing the transmitter with the filtered desired transmit time delay.

14. The method of claim 1 , further comprising providing the transmitter of the signal of interest, with the pattern.

15. A method of coordinating wireless transmission of a signal of interest, wherein the signal of interest includes multi-carrier symbols, between a transmitter and a receiver, comprising:

measuring, by the receiver, a received signal power of a receive signal through a select band of a frequency hopping sequence over time, wherein the receive signal includes the signal of interest and an interfering signal, wherein the interfering signal comprises interfering multi-carrier symbols;

identifying a pattern of the interfering multi-carrier symbols of the interfering signal from the received signal power;

adjusting a desired transmit time delay of the signal of interest based on characteristics of the pattern; and

adjusting, by the transmitter, a timing of transmission of the multi-carrier symbols by the desired transmit time delay.

16. The method of claim 15 , further comprising estimating a Signal to Interference and Noise Ratio (SINR) for each sub-carrier of the multi-carrier symbols based on the pattern, the received signal power, an interference signal power, and a channel response of the signal of interest.

17. The method of claim 16 , further comprising estimating the channel response of the interfering signal based on the pattern.

18. The method of claim 16 , further comprising estimating a received Packet Error Rate (PER) based on the SINR for each sub-carrier of the multi-carrier symbols and coding of information of the sub-carriers of the multi-carrier symbols at the transmitter.

19. The method of claim 18 , further comprising:

adjusting the desired transmit time delay to reduce the estimated PER of the signal of interest.
