Abstract
An extended bandwidth HomePNA system uses a transmit spectrum having a greater bandwidth than the bandwidth specified by a HomePNA 2.0 communication standard. The extended bandwidth system of the invention provides for additional copies of a spectrum of a 2 Mbaud training signal for better accuracy in decoding transmitted data by a receiver. In one embodiment, the extended bandwidth is a 12 MHz band centered at 10 MHz, from 4 MHz to 16 MHz. This extended bandwidth allows for three copies of a 4 Mbaud training sequence or six copies of a 2 Mbaud training sequence. The extended bandwidth of the invention is compatible with a HomePNA 2.0 system by providing a training sequence that enables a HomePNA 2.0 receiver in 2 Mbaud mode to train on the transmitted signal and determine that the transmitted signal is not intended for the HomePNA 2.0 receiver in 2 Mbaud mode.
