System and method for minimizing signal interference between broadcasting signals and communication signals within local area and apparatus applied to the same

摘要

Disclosed is a system and a method for minimizing signal interference for a broadcasting and communication convergence section within a local area, and an apparatus applied to the same. The system has a construction of mounting a plurality of multi RF (Radio Frequency) channels within a local area wireless communication apparatus located in a local area and minimizing signal interference between mutually adjacent RF channels within the local area wireless communication apparatus in a standard for providing a broadcasting and communication convergence service. Accordingly, it is possible to remove the mutual channel effects affecting a communication signal without signal interference for adjacent channels due to a broadcasting signal and it is not necessary to enhance a filtering characteristic for the adjacent channels of a chipset, which corresponds to a broadcasting and communication convergence standard structure in a local area, so that there is an advantage of reducing network investment costs.

主权项

1. A local area wireless communication apparatus, comprising:
two or more local area wireless communication units configured to transmit broadcasting signals to a local area through two or more radio frequency (RF) channels and to communicate communication signals with one or more user terminal apparatuses located in the local area through one RF channel of the two or more RF channels, wherein the broadcasting signals are unidirectional signals to the one or more user terminal apparatuses and the communication signals are bidirectional signals to and from the one or more user terminal apparatuses; and a controller configured
to synchronize two or more broadcasting frames for the broadcasting signals allocated onto each of the two or more RF channels on a time axis, and,when one bidirectional communication frame for the communication signals has been allocated onto the one RF channel of the two or more RF channels, to allocate other bidirectional communication frames for the communication signals onto other RF channels of the two or more RF channels to thereby synchronize the allocated other bidirectional communication frames with the one bidirectional communication frame on the time axis.
