A first network device determines whether a first reference code included in at least a first transmission on a communication channel is associated with a code configured in the first network device. The communication channel is shared among a plurality of communication networks and the first reference code is associated with a first communication network of the plurality of communication networks. The first network device joins the first communication network associated with the first reference code in response to determining the first reference code is associated with the code configured in the first network device. The first network device communicates with a second network device in the first communication network using the code configured in the first network device.

Channel reuse among communication networks sharing a communication channel

This disclosure provides several mechanisms for adapting transmit power spectral density (PSD). A communications device may adapt the power spectrum utilized at the transmitter based, at least in part, on the channel conditions or PSD constraints associated with the communications medium between the transmitter and a receiver device. Additionally, the transmit PSD may be adapted based, at least in part, on a total power capability associated with a transmitter. Power is allocated to improve throughput and utilization of the communications channel. A transmission profile may be selected based, at least in part, on the notch depth. The transmission profile may be associated with symbol timing parameters. The communications device may maintain a plurality of selectable pulse shapes that are optimized for different notch depths.
