A communication device (device) includes a processor configured to generate an initial ranging LDPC coded signal based on a first LDPC code and then transmits the initial ranging LDPC coded signal to another device (e.g., via a communication interface) for use by the other device for coarse power and timing adjustment. Then, the processor processes a received transmit opportunity signal to identify a transmit opportunity time period. The processor then generates a fine ranging LDPC coded signal based on a second LDPC code and transmits the fine ranging LDPC coded signal to the other device during the transmit opportunity time period for use by the other device for fine power and timing adjustment. In some instances, the processor may be configured to generate one or more wideband probe signals for transmission to the other device in conjunction with or instead of the fine ranging LDPC coded signals.
