Method and apparatus for transmitting a gigabit-ethernet signal by a high capacity point-to-point radio system

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.

1. An apparatus for transmitting a Gigabit-Ethernet signal through a fixed high capacity point-to-point radio system, the apparatus comprising:
a user interface for receiving a Gigabit-Ethernet signal to be transmitted; means for selecting a transmission carrier frequency and an associated bandwidth, wherein said carrier frequency is in a range of 6 to 38 GHz and said associated bandwidth is less than 1.25 GHz; a compression rate selector for compressing the Gigabit-Ethernet signal to be transmitted by a compression rate of 1:8, thus obtaining a compressed Gigabit-Ethernet signal, wherein the step of compressing comprises selecting a compression rate according to resources which are available in the radio link; a mapper for mapping the compressed Gigabit-Ethernet signal in a single virtual container; and a transceiver means for transmitting the single virtual container through said fixed high capacity point-to-point radio system.
