METHOD AND APPARATUS FOR USING NON-SYMMETRIC SPEECH CODERS TO PRODUCE NON-SYMMETRIC LINKS IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for balancing the forward link capacity of a wireless communication system with the reverse link capacity of the system is presented. Speech coder with selectable modes are implemented in both links so that a forward link speech coder will not be operating with a mode set that is identical to the mode set used by a reverse link speech coder. Since the reverse link has a higher user capacity than a forward link, the reverse link speech coder can operate with a higher average data rate. Hence, the mode set used by the reverse link speech coder can be implemented without low average data rate modes. Elimination of modes from the mode set reduces complexity of the speech coder.
