摘要
A method and apparatus are described for transmitting/receiving a Gigabit-Ethernet signal by a high capacity point-to-point radio system. The basic idea consists in transmitting a Gigabit Ethernet interface using a single frequency in a channel plan of about 56 MHz bandwidth. The invention is based on a technology that combines forward error correction, cross polarization interference cancellation (XPIC), base-band signal processing, adaptive equalization and antenna's interconnection. In the best configuration, two carrier frequencies, H and V polarized, are selected in order to have the required bandwidth for easily transporting a Gigabit Ethernet. A proper compression rate can be selected according to the available resources; in case of radio channel failure, the compression rate can be changed. Ethernet frames are mapped by a Generic Framing Procedure encapsulation protocol.
