METHOD FOR TRANSMITTING MULTIPLE STREAMS IN WIRELESS BROADCAST NETWORKS

摘要

PROBLEM TO BE SOLVED: To provide a method for managing broadcast resources to reduce the coverage hole. SOLUTION: The method includes: converting received content into a first stream and a second stream; transmitting the first stream using a first tone; and transmitting the second stream using an orthogonal scheme. A layering scheme is used to transmit the base stream covering a smaller area, and an enhanced stream is used to cover a lager area utilizing an orthogonal scheme. COPYRIGHT: (C)2011,JPO&INPIT
