ABSTRACT:
Method and system for enhancing channel capacity in a Point-to Multipoint radio communications system that includes terminal stations (12) of different kinds, such as residential terminals and business terminals, with different link budget requirements i.e. different signal-to-noise ratio. The method is characterized by the selective use of different channel coding codes such as forward error correction (FEC) codes, in the different concurrent channels, depending on a pre-defined category of an addressed subscriber. The multiplexing method used may be CDMA (Code Division Multiple Access) and TDMA (Time Division Multiple Access). Each terminal station (12) is in turn equipped only with an appropriate decoder, depending on its kind, e.g. residential or business.
