Abstract:
A method for providing one or more classes of communication services for one or more users through a shared wired communication channel, the users being connected to the communication channel via a multiple access node, the method comprising the steps of:orthogonally encoding an incoming information stream sent by each user by an encoding modem using a multi-class encoding process; wherein the step of orthogonally encoding further includes the steps of splitting the incoming information stream into one or more classes, each class representing a first level sub stream of information; dividing each first level sub stream into a plurality of second level sub streams of information; encoding the second level sub streams with a predetermined set of orthogonal codes according to a predetermined code plan; modulating each encoded sub stream by a modulating signal; and combining the modulated sub streams into one fully encoded data stream; and transmitting the encoded information through the multiple access node to the shared wired communication channel; wherein the multi-class encoding process is implemented according to the predetermined code plan designating specific orthogonal codes for each class of communication service.
