Abstract
A communication system receives and codes a plurality of information signals according to coding assignments to produce a plurality of coded baseband signals. From these signals, a simulated composite carrier signal is formed which has all the characteristics of an actual composite carrier signal which would have resulted if the plurality of coded baseband signals had been formed. The simulated composite carrier signal is analyzed to determine its peak-to-average ratio. The communication system selects a different coding assignments for coding the plurality of information signals if, based on the determined peak-to-average ratio and a selection criteria, the coding assignment does not produce the desired results. The communication system selects a different coding assignments until at least one or several desired coding techniques have been identified, ranks the coding techniques and makes a final selection of the coding technique to meet the peak-to-average ratio requirements.
