Abstract: An architecture defining functional and technical perimeters to be complied with between two subsystems termed “baseband” and “radio frequency,” and to a generic physical interconnection pattern between baseband and radio frequency, which, under nominal operation, does not require physical signals specific to the design of one or other of the baseband and radio frequency subsystems, and which is not associated with a particular physical implementation solution. The architecture uses an exchange protocol which travels over the generic interface, meeting the real-time constraints of the transmission systems and using a time stamped messaging system.

Abstract: A transmitter for a radio transmission system has an encoder for encoding data according to an error correction code and supplying a digital output stream of bits which are then distributed over a selectable number of carriers belonging to a group of carriers that are uniformly distributed over a transmission channel, so as to constitute a frequency division multiplex. Then the stream is subjected to time interleaving responsive to a distribution given by the bit spreading module which achieves distribution and frequency interleaving operating on the carriers; the stream is then modulated in phase or possibly a phase and amplitude.
