摘要： A method and an apparatus transmit and receive information in a cable TV network including at least one base station connected to a branching cable network, branching from the base station to at least two subscribers, provided with transmitters. A unique carrier frequency is assigned to each of the subscriber's transmitters, the carrier frequencies being orthogonal. Signals from the subscriber's transmitters are transmitted simultaneously, received in the base station as a broadband signal, and separated using a common algorithm.
