Title:
帯域外漏洩干渉を抑制する方法及びシステム
Document Type and Number:
Japanese Patent JP5855758
Kind Code:
B2
Abstract:
Disclosed are a method and system for suppressing out-of-band leakage interference, for solving the technical problem that the existing usage method of the guard band cannot reduce the guard bandwidth among specific systems. In the present invention, a low-medium-power terrestrial television broadcast transmission channel is used to share site addresses with a terrestrial mobile communication system, avoiding the occurrence of out-of-band leakage power of the conventional large-power terrestrial broadcast transmitter, thus greatly reducing the width of the guard band between the terrestrial television broadcast band and the terrestrial mobile communication system; at a shared site address, a part of bands allocated for use by the mobile communication uplink channel are used as the isolation bands between the low-medium-power terrestrial television broadcast transmission channel and the terrestrial mobile communication system at the shared site address, reducing the interference to the mobile communication uplink channel by the out-of-band leakage power of the terrestrial television broadcast transmission channel.
