Equipment for optimising a multicarrier modulation transmission system, comprises one multicarrier modulator which favors a minimum error rate and a second which favors maximum information flow

摘要

A data source (10) supplies data blocks to an insertion unit.(20) which places them in one of two multicarrier modulators (40,50) designed to favor either minimum error or maximum data flow. A control signal (15) directs the insertion unit where to place data according to their importance and operates multiplexors(30,60) such that the chosen modulator is used to send the data to a radio frequency interface (70)
