METHOD AND APPARATUS FOR MINIMIZING CO-CHANNEL INTERFERENCE

摘要

An approach is provided for minimizing co-channel interference in a communication system (100) is disclosed. A header (401) of a first frame is scrambled based on a first unique word (411, 413). A header (401) of a second frame is scrambled based on a second unique word (411, 413). The first frame including the corresponding scrambled header (401) and the second frame including the corresponding scrambled header (401) are transmitted, respectively, over adjacent co-channels of the communication system (100). Each of the frames further includes a payload (403) and a pilot block (405). The payload (403) and the pilot black (405) of the first frame are scrambled based on a first scrambling sequence. The payload (403) and the pilot black (405) of the second frame are scrambled based on a second scrambling sequence. The above arrangement is particularly suited to a digital satellite broadcast and interactive system (100).
