Abstract: A communication device includes a communication interface and a processor. In one example, the processor generates an orthogonal frequency division multiplexing (OFDM) symbol that includes information modulated within sub-carriers and then interleaves the sub-carriers of the OFDM symbol to generate an interleaved OFDM symbol. This interleaving of the sub-carriers operates to write the plurality of sub-carriers to rows of a two dimensional (2D) array and read the plurality of sub-carriers from columns of the 2D array. This interleaving also operates to read a column of the columns using a bit-reversed address of the column when the bit-reversed address is less than a number of the columns and using the address of the column when the bit-reversed address is greater than or equal to the number of the columns. The processor transmits, via the communication interface, the interleaved OFDM symbol to another communication device.

Abstract: A communication device includes a communication interface, a number of variable power amplifiers (VPAs), and a processor. Some of the VPAs are configured to process analog signals to generate processed analog signals (e.g., each VPA configured to process one of the analog signals to generate one of the processed analog signals based on a respective VPA control signal). A composite VPA processes a summation of the processed analog signals, which are generated by certain of the VPA, to generate a processed composite signal based on a composite VPA control signal. The processor generates the a first, a second, and a composite VPA control signals based, at least in part, on configuration information from another communication device via the communication interface. The processor may be configured to consider other information as well, such as locally generated information (within the communication device), operational history, current operating conditions, etc.

Abstract: A communication device is configured to communicate coded information to other communication device(s). The communication device uses NCPs to indicate locations of codewords within signal(s) transmitted to the other communication device(s). The communication device is configured to encode NCP(s) using an FEC code to generate coded NCP(s) and also to encode the NCP(s) using a cyclic redundancy check (CRC) code to generate NCP CRC bits. The communication device is also configured to encode the NCP CRC bits using the FEC code to generate coded NCP CRC bits. The communication device is then configured to generate OFDM or OFDMA symbol(s) include the coded NCP(s) and the coded NCP CRC bits to indicate beginnings of codeword(s) within at least one of the OFDM symbol(s) and/or additional OFDM symbol(s). The communication device is also configured to transmit the OFDM or OFDMA symbols to another communication device via a communication interface of the communication device.

Abstract: 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 transit 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.
