Abstract: A technique for communicating multimedia data between nodes over coaxial cable, wherein the nodes are connected via a coaxial cable network, is disclosed. In an embodiment, the technique involves establishing a primary channel for communicating between first and second nodes of the coaxial cable network, establishing a secondary channel for communicating between the first and second nodes of the coaxial cable network, wherein the primary and secondary channels are in different frequency bands and wherein the primary channel is used for communicating media access control frames, and communicating a time series of data frames between the first and second nodes using both the primary channel and the secondary channel.

Abstract: A 10 MHz channelized orthogonal frequency division multiplexing (OFDM) transmitter is provided that communicates using a modified OFDM packet structure with a half-rate oscillator having standard accuracy. The transmitter has an inverse fast fourier transform (IFFT) data processor that appends an outer pair of data subcarriers on either end of an OFDM subcarrier profile. An IFFT long sync processor appends an outer pair of binary phase shift key (BPSK) subcarriers on either end of an OFDM long sync subcarrier profile. By copying or appending the information of the data subcarriers closest to zero Hz. to more robust locations, 10 MHz channelized OFDM can be achieved with half-rate clocks and 20 PPM oscillators.

Abstract: A power-based hardware antenna diversity method for a wireless transceiver with multiple antennas is disclosed. The method is characterized in the steps of setting the transceiver gain at a maximum level to establish a first story of dynamic power range above a noise floor level, using a high-resolution ADC at a large back-off level relative to the noise floor to detect weak signals within the first story of the dynamic power range, switching antennas and measuring power level for each antenna during signal onset, and selecting an antenna having a largest power level.
